“II. (6) "And when the angels of God saw the daughters of men that they were beautiful, they took unto themselves wives of all of them whom they Chose." [Genesis 6:2] Those beings, whom other philosophers call demons, Moses usually calls angels; and they are souls hovering in the air. (7) And let no one suppose, that what is here stated is a fable, for it is necessarily true that the universe must be filled with living things in all its parts, since every one of its primary and elementary portions contains its appropriate animals and such as are consistent with its nature; --the earth containing terrestrial animals, the sea and the rivers containing aquatic animals, and the fire such as are born in the fire (but it is said, that such as these last are found chiefly in Macedonia), and the heaven containing the stars: (8) for these also are entire souls pervading the universe, being unadulterated and divine, inasmuch as they move in a circle, which is the kind of motion most akin to the mind, for every one of them is the parent mind. It is therefore necessary that the air also should be full of living beings. And these beings are invisible to us, inasmuch as the air itself is not visible to mortal sight. (9) But it does not follow, because our sight is incapable of perceiving the forms of souls, that for that reason there are no souls in the air; but it follows of necessity that they must be comprehended by the mind, in order that like may be contemplated by like. (10) Since what shall we say? Must we not say that these animals which are terrestrial or aquatic live in air and spirit? What? Are not pestilential afflictions accustomed to exist when the air is tainted or corrupted, as if that were the cause of all such assuming vitality? Again, when the air is free from all taint and innocent, such as it is especially wont to be when the north wind prevails, does not the imbibing of a purer air tend to a more vigorous and more lasting duration of life? (11) It is then natural that that medium by which all other animals, whether aquatic of terrestrial, are vivified should itself be empty and destitute of souls? On the contrary, even if all other animals were barren, the air by itself would be bound to be productive of life, having received from the great Creator the seeds of vitality by his especial favour. III. (12) Some souls, therefore, have descended into bodies, and others have not thought worthy to approach any one of the portions of the earth; and these, when hallowed and surrounded by the ministrations of the father, the Creator has been accustomed to employ, as hand-maidens and servants in the administration of mortal affairs. (13) And they having descended into the body as into a river, at one time are carried away and swallowed up by the voracity of a most violent whirlpool; and, at another time, striving with all their power to resist its impetuosity, they at first swim on the top of it, and afterwards fly back to the place from which they started. (14) These, then, are the souls of those who have been taught some kind of sublime philosophy, meditating, from beginning to end, on dying as to the life of the body, in order to obtain an inheritance of the incorporeal and imperishable life, which is to be enjoyed in the presence of the uncreate and everlasting God. (15) But those, which are swallowed up in the whirlpool, are the souls of those other men who have disregarded wisdom, giving themselves up to the pursuit of unstable things regulated by fortune alone, not one of which is referred to the most excellent portion of us, the soul or the mind; but all rather to the dead corpse connected with us, that is to the body, or to things which are even more lifeless than that, such as glory, and money, and offices, and honours, and all other things which, by those who do not keep their eyes fixed on what is really beautiful, are fashioned and endowed with apparent vitality by the deceit of vain opinion. IV. (16) If, therefore, you consider that souls, and demons, and angels are things differing indeed in name, but not identical in reality, you will then be able to discard that most heavy burden, superstition. But as men in general speak of good and evil demons, and in like manner of good and evil souls, so also do they speak of angels, looking upon some as worthy of a good appellation, and calling them ambassadors of man to God, and of God to man, and sacred and holy on account of this blameless and most excellent office; others, again, you will not err if you look upon as unholy and unworthy of any address. (17) And the expression used by the writer of the psalm, in the following verse, testifies to the truth of my assertion, for he says, "He sent upon them the fury of His wrath, anger, and rage, and affliction, and he sent evil angels among Them." [Ps 77:49] These are the wicked who, assuming the name of angels, not being acquainted with the daughters of right reason, that is with the sciences and the virtues, but which pursue the mortal descendants of mortal men, that is the pleasures, which can confer no genuine beauty, which is perceived by the intellect alone, but only a bastard sort of elegance of form, by means of which the outward sense is beguiled; (18) and they do not all take all the daughters in marriage, but some of them have selected some of that innumerable company to be their wives; some choosing them by the sight, and others by the ear, others again being influenced by the sense of taste, or by the belly, and some even by the pleasures below the belly; many also have laid hold of those the abode of which is fixed at a great distance, putting in action various desires among one another. For, of necessity, the choices of all the various pleasures are various, since different pleasures are established in different places.”

“For many angels of God accompanied with women, and begat sons that proved unjust, and despisers of all that was good, on account of the confidence they had in their own strength; for the tradition is, that these men did what resembled the acts of those whom the Grecians call giants. But Noah was very uneasy at what they did; and being displeased at their conduct, persuaded them to change their dispositions and their acts for the better: but seeing they did not yield to him, but were slaves to their wicked pleasures, he was afraid they would kill him, together with his wife and children, and those they had married; so he departed out of that land.”

“God, when He had made the whole world, and subjected things earthly to man, and arranged the heavenly elements for the increase of fruits and rotation of the seasons, and appointed this divine law-for these things also He evidently made for man-committed the care of men and of all things under heaven to angels whom He appointed over them. But the angels transgressed this appointment, and were captivated by love of women, and begat children who are those that are called demons; and besides, they afterwards subdued the human race to themselves, partly by magical writings, and partly by fears and the punishments they occasioned, and partly by teaching them to offer sacrifices, and incense, and libations, of which things they stood in need after they were enslaved by lustful passions; and among men they sowed murders, wars, adulteries, intemperate deeds, and all wickedness. Whence also the poets and mythologists, not knowing that it was the angels and those demons who had been begotten by them that did these things to men, and women, and cities, and nations, which they related, ascribed them to god himself, and to those who were accounted to be his very offspring, and to the offspring of those who were called his brother), Neptune and Pluto, and to the children again of these their offspring. For whatever name each of the angels had given to himself and his children, by that name they called them.”

“And for a very long while wickedness extended and spread, and reached and laid hold upon the whole race of mankind, until a very small seed of righteousness remained among them: and illicit unions took place upon the earth, since angels were united with the daughters of the race of mankind; and they bore to them sons who for their exceeding greatness were called giants. And the angels brought as presents to their wives teachings of wickedness, in that they brought them the virtues of roots and herbs, dyeing in colours and cosmetics, the discovery of rare substances, love-potions, aversions, amours, concupiscence, constraints of love, spells of bewitchment, and all sorcery and idolatry hateful to God; by the entry of which things into the world evil extended and spread, while righteousness was diminished and enfeebled. Until judgment came upon the world from God by means of a flood, in the tenth generation from the first-formed (man); Noah alone being found righteous.”

“Since the Son of God is always one and the same, He gives to those who believe on Him a well of water [springing up] to eternal life, but He causes the unfruitful fig-tree immediately to dry up; and in the days of Noah He justly brought on the deluge for the purpose of extinguishing that most infamous race of men then existent, who could not bring forth fruit to God, since the angels that sinned had commingled with them, and [acted as He did] in order that He might put a check upon the sins of these men, but [that at the same time] He might preserve the archetype, the formation of Adam. And it was He who rained fire and brimstone from heaven, in the days of Lot, upon Sodom and Gomorrah, "an example of the righteous judgment of God," that all may know, "that every tree that bringeth not forth good fruit shall be cut down, and cast into the fire."”

“The mind is led astray by pleasure, and the virgin center of the mind, if not disciplined by the Word, degenerates into licentiousness and reaps disintegration as reward for its transgressions. An example of this for you is the angels who forsook the beauty of God for perishable beauty and fell as far as heaven is from the earth.”

“To which also we shall add, that the angels who had obtained the superior rank, having sunk into pleasures, told to the women the secrets which had come to their knowledge; while the rest of the angels concealed them, or rather, kept them against the coming of the Lord.”

Tertullian Patristic
c. A.D. 150–220
“For they, withal, who instituted them are assigned, under condemnation, to the penalty of death — those angels, to wit, who rushed from heaven on the daughters of men; so that this ignominy also attaches to woman. For when to an age much more ignorant (than ours) they had disclosed certain well-concealed material substances, and several not well-revealed scientific arts — if it is true that they had laid bare the operations of metallurgy, and had divulged the natural properties of herbs, and had promulgated the powers of enchantments, and had traced out every curious art, even to the interpretation of the stars — they conferred properly and as it were peculiarly upon women that instrumental mean of womanly ostentation, the radiances of jewels wherewith necklaces are variegated, and the circlets of gold wherewith the arms are compressed, and the medicaments of orchil with which wools are colored, and that black powder itself wherewith the eyelids and eyelashes are made prominent. What is the quality of these things may be declared meantime, even at this point, from the quality and condition of their teachers: in that sinners could never have either shown or supplied anything conducive to integrity, unlawful lovers anything conducive to chastity, renegade spirits anything conducive to the fear of God. If (these things) are to be called teachings, ill masters must of necessity have taught ill; if as wages of lust, there is nothing base of which the wages are honourable. But why was it of so much importance to show these things as well as to confer them? Was it that women, without material causes of splendour, and without ingenious contrivances of grace, could not please men, who, while still unadorned, and uncouth and — so to say — crude and rude, had moved (the mind of) angels? Or was it that the lovers would appear sordid and — through gratuitous use — contumelious, if they had conferred no (compensating) gift on the women who had been enticed into connubial connection with them? But these questions admit of no calculation. Women who possessed angels (as husbands) could desire nothing more; they had, forsooth, made a grand match! Assuredly they who, of course, did sometimes think whence they had fallen, and, after the heated impulses of their lusts, looked up toward heaven, thus requited that very excellence of women, natural beauty, as (having proved) a cause of evil, in order that their good fortune might profit them nothing; but that, being turned from simplicity and sincerity, they, together with (the angels) themselves, might become offensive to God. Sure they were that all ostentation, and ambition, and love of pleasing by carnal means, was displeasing to God. And these are the angels whom we are destined to judge: these are the angels whom in baptism we renounce: these, of course, are the reasons why they have deserved to be judged by man. What business, then, have their things with their judges? What commerce have they who are to condemn with them who are to be condemned? The same, I take it, as Christ has with Belial. With what consistency do we mount that (future) judgment-seat to pronounce sentence against those whose gifts we (now) seek after? For you too, (women as you are,) have the self-same angelic nature promised as your reward, the self-same sex as men: the self-same advancement to the dignity of judging, does (the Lord) promise you. Unless, then, we begin even here to pre-judge, by pre-condemning their things, which we are hereafter to condemn in themselves, they will rather judge and condemn us.”

“What is "every woman, but woman of every age, of every rank, of every condition? By saying" every" he excepts nought of womanhood, just as he excepts nought of manhood either from not being covered; for just so he says, "Every man." As, then, in the masculine sex, under the name of" man" even the" youth" is forbidden to be veiled; so, too, in the feminine, under the name of "woman," even the "virgin" is bidden to be veiled. Equally in each sex let the younger age follow the discipline of the elder; or else let the male "virgins," too, be veiled, if the female virgins withal are not veiled, because they are not mentioned by name. Let "man" and "youth" be different, if "woman" and "virgin" are different. For indeed it is "on account of the angels" that he saith women must be veiled, because on account of "the daughters of men" angels revolted from God.”

“When men multiplied on the earth, the angels of heaven came together with the daughters of men. In some copies I found "the sons of God." What is meant by the Spirit, in my opinion, is that the descendants of Seth are called the sons of God on account of the righteous men and patriarchs who have sprung from him, even down to the Saviour Himself; but that the descendants of Cain are named the seed of men, as having nothing divine in them, on account of the wickedness of their race and the inequality of their nature, being a mixed people, and having stirred the indignation of God. But if it is thought that these refer to angels, we must take them to be those who deal with magic and jugglery, who taught the women the motions of the stars and the knowledge of things celestial, by whose power they conceived the giants as their children, by whom wickedness came to its height on the earth, until God decreed that the whole race of the living should perish in their impiety by the deluge.”

“But when they did nothing of this kind, but tried to make supplication to the evil daemons by a foul and licentious life and unseemly words, and by feeding on raw flesh, and rending victims asunder, and by human sacrifices, how was it even possible that doing such deeds, and pursuing practices pleasing to the wicked, they should be received as friends by the Supreme God, or by the divine Powers subject to Him, or by any good beings at all? But in fact it is manifest to all that he who practises the things that are dear to the wicked can never be a friend of the good. So then it was not to gods, nor yet to good daemons, but only to the wicked, that those of whom I have spoken paid worship. And this argument is still further confirmed by Plutarch, in the passage where he says that the mythical narratives told as concerning gods are certain tales about daemons, and the deeds of Giants and Titans celebrated in song among the Greeks are also stories about daemons, intended to suggest a new phase of thought. Of this kind then perhaps were the statements in the Sacred Scripture concerning the giants before the flood, and those concerning their progenitors, of whom it is said, 'And when the angels of God saw the daughters of men that they were fair, they took unto them wives of all that they chose,' and of these were born 'the giants the men of renown which were of old.' For one might say that these daemons are those giants, and that their spirits have been deified by the subsequent generations of men, and that their battles, and their quarrels among themselves, and their wars are the subjects of these legends that are told as of gods.”

“"Now, when the sons of God saw that the daughters of men were beautiful, they took wives for themselves from them all just as they were inclined." Let us study each expression of this statement closely so that nothing of what is hidden below the surface may pass us by. You see, there is need to make a careful study of this passage and confute the fanciful interpretations of those people whose every remark is made rashly - firstly, to repeat what they presume to say, and by demonstrating the absurdity of what is said by them to teach your good selves the true sense of Scripture so that you will not lend your ears idly to people uttering those blasphemies and presuming to speak in a way that brings their own persons into jeopardy. I mean, they claim that this remark is made not about human being but about angels; these (they say) he called sons of God. Let them demonstrate firstly where angels are called sons of God; they would not, however, be able to show this anywhere. While human beings are called sons of God, angels are nowhere so called. On the contrary, it speaks about angels in these terms: "He makes the winds his angels, fire and flame his ministers," whereas about human beings, "I said, You are gods," and again, "Sons have I begotten and raised," and again, "Israel my firstborn son" - but an angel is nowhere called son, or son of God. What in fact do they claim? To be sure, they really were angels, but because they fell into this lawless way, they lost their status... Is it not a particular hallmark of folly to claim that angels descended to have intercourse with women, and that incorporeal nature of theirs was reduced to association with corporeal creatures? Or do you not hear the words of Christ about the being of angels, "At the resurrection they neither marry nor are given in marriage, but are like angels of God"? After all, it is not for that kind of incorporeal creature to ever feel the onset of desire. In response to these people we have to reach the same conclusion, that to admit this notion into one's mind is the height of absurdity. We made the point before in teaching you that it is customary with Scripture to call human beings sons of God. So since these people took their origin from Seth and from his son named Enosh (the text, remember, saying, "He it was who hoped to invoke the name of the Lord God"), those descended from him in the future were called sons of God by Sacred Scripture for the reason of their imitation of the virtue of their ancestors up to his time. On the other hand, he gave the name sons of men to those born after Seth, the descendants of Cain and those taking their descent from him.”

“In the third book of this work we made a passing reference to this question, but did not decide whether angels, inasmuch as they are spirits, could have bodily intercourse with women. For it is written, "Who makes His angels spirits," that is, He makes those who are by nature spirits His angels by appointing them to the duty of bearing His messages. For the Greek word ἄγγελος, which in Latin appears as "angelus," means a messenger. But whether the Psalmist speaks of their bodies when he adds, "and His ministers a flaming fire," or means that God's ministers ought to blaze with love as with a spiritual fire, is doubtful. However, the same trustworthy Scripture testifies that angels have appeared to men in such bodies as could not only be seen, but also touched. There is, too, a very general rumor, which many have verified by their own experience, or which trustworthy persons who have heard the experience of others corroborate, that sylvans and fauns, who are commonly called "incubi," had often made wicked assaults upon women, and satisfied their lust upon them; and that certain devils, called Duses by the Gauls, are constantly attempting and effecting this impurity is so generally affirmed, that it were impudent to deny it. From these assertions, indeed, I dare not determine whether there be some spirits embodied in an aerial substance (for this element, even when agitated by a fan, is sensibly felt by the body), and who are capable of lust and of mingling sensibly with women; but certainly I could by no means believe that God's holy angels could at that time have so fallen, nor can I think that it is of them the Apostle Peter said, "For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment." [2 Peter 2:4] I think he rather speaks of these who first apostatized from God, along with their chief the devil, who enviously deceived the first man under the form of a serpent. But the same holy Scripture affords the most ample testimony that even godly men have been called angels; for of John it is written: "Behold, I send my messenger (angel) before Your face, who shall prepare Your way." [Mark 1:2] And the prophet Malachi, by a peculiar grace specially communicated to him, was called an angel. [Malachi 2:7] But some are moved by the fact that we have read that the fruit of the connection between those who are called angels of God and the women they loved were not men like our own breed, but giants; just as if there were not born even in our own time (as I have mentioned above) men of much greater size than the ordinary stature. Was there not at Rome a few years ago, when the destruction of the city now accomplished by the Goths was drawing near, a woman, with her father and mother, who by her gigantic size over-topped all others? Surprising crowds from all quarters came to see her, and that which struck them most was the circumstance that neither of her parents were quite up to the tallest ordinary stature. Giants therefore might well be born, even before the sons of God, who are also called angels of God, formed a connection with the daughters of men, or of those living according to men, that is to say, before the sons of Seth formed a connection with the daughters of Cain. For thus speaks even the canonical Scripture itself in the book in which we read of this; its words are: "And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them, that the sons of God saw the daughters of men that they were fair [good]; and they took them wives of all which they chose. And the Lord God said, My Spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years. There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became the giants, men of renown." These words of the divine book sufficiently indicate that already there were giants in the earth in those days, in which the sons of God took wives of the children of men, when they loved them because they were good, that is, fair. For it is the custom of this Scripture to call those who are beautiful in appearance "good." But after this connection had been formed, then too were giants born. For the words are: "There were giants in the earth in those days, and also after that, when the sons of God came in unto the daughters of men." Therefore there were giants both before, "in those days," and "also after that." And the words, "they bare children to them," show plainly enough that before the sons of God fell in this fashion they begot children to God, not to themselves — that is to say, not moved by the lust of sexual intercourse, but discharging the duty of propagation, intending to produce not a family to gratify their own pride, but citizens to people the city of God; and to these they as God's angels would bear the message, that they should place their hope in God, like him who was born of Seth, the son of resurrection, and who hoped to call on the name of the Lord God, in which hope they and their offspring would be co-heirs of eternal blessings, and brethren in the family of which God is the Father. But that those angels were not angels in the sense of not being men, as some suppose, Scripture itself decides, which unambiguously declares that they were men. For when it had first been stated that "the angels of God saw the daughters of men that they were fair, and they took them wives of all which they chose," it was immediately added, "And the Lord God said, My Spirit shall not always strive with these men, for that they also are flesh." For by the Spirit of God they had been made angels of God, and sons of God; but declining towards lower things, they are called men, a name of nature, not of grace; and they are called flesh, as deserters of the Spirit, and by their desertion deserted [by Him]. The Septuagint indeed calls them both angels of God and sons of God, though all the copies do not show this, some having only the name sons of God. And Aquila, whom the Jews prefer to the other interpreters, has translated neither angels of God nor sons of God, but sons of gods. But both are correct. For they were both sons of God, and thus brothers of their own fathers, who were children of the same God; and they were sons of gods, because begotten by gods, together with whom they themselves also were gods, according to that expression of the psalm: "I have said, You are gods, and all of you are children of the Most High." For the Septuagint translators are justly believed to have received the Spirit of prophecy; so that, if they made any alterations under His authority, and did not adhere to a strict translation, we could not doubt that this was divinely dictated. However, the Hebrew word may be said to be ambiguous, and to be susceptible of either translation, "sons of God," or "sons of gods." Let us omit, then, the fables of those scriptures which are called apocryphal, because their obscure origin was unknown to the fathers from whom the authority of the true Scriptures has been transmitted to us by a most certain and well-ascertained succession. For though there is some truth in these apocryphal writings, yet they contain so many false statements, that they have no canonical authority. We cannot deny that Enoch, the seventh from Adam, left some divine writings, for this is asserted by the Apostle Jude in his canonical epistle. But it is not without reason that these writings have no place in that canon of Scripture which was preserved in the temple of the Hebrew people by the diligence of successive priests; for their antiquity brought them under suspicion, and it was impossible to ascertain whether these were his genuine writings, and they were not brought forward as genuine by the persons who were found to have carefully preserved the canonical books by a successive transmission. So that the writings which are produced under his name, and which contain these fables about the giants, saying that their fathers were not men, are properly judged by prudent men to be not genuine; just as many writings are produced by heretics under the names both of other prophets, and more recently, under the names of the apostles, all of which, after careful examination, have been set apart from canonical authority under the title of Apocrypha. There is therefore no doubt that, according to the Hebrew and Christian canonical Scriptures, there were many giants before the deluge, and that these were citizens of the earthly society of men, and that the sons of God, who were according to the flesh the sons of Seth, sunk into this community when they forsook righteousness. Nor need we wonder that giants should be born even from these. For all of their children were not giants; but there were more then than in the remaining periods since the deluge. And it pleased the Creator to produce them, that it might thus be demonstrated that neither beauty, nor yet size and strength, are of much moment to the wise man, whose blessedness lies in spiritual and immortal blessings, in far better and more enduring gifts, in the good things that are the peculiar property of the good, and are not shared by good and bad alike. It is this which another prophet confirms when he says, "These were the giants, famous from the beginning, that were of so great stature, and so expert in war. Those did not the Lord choose, neither gave He the way of knowledge unto them; but they were destroyed because they had no wisdom, and perished through their own foolishness."”

“As long then as there continued that separation of the lines between them, the seed of Seth, as it sprang from an excellent root, was by reason of its sanctity termed "angels of God," or as some copies have it "sons of God;" and on the contrary the others by reason of their own and their fathers' wickedness and their earthly deeds were termed "children of men." Though then there was up to this time that holy and salutary separation between them, yet after this the sons of Seth who were the sons of God saw the daughters of those who were born of the line of Cain, and inflamed with the desire for their beauty took to themselves from them wives who taught their husbands the wickedness of their fathers, and at once led them astray from their innate holiness and the single-mindedness of their forefathers...From these sons of Seth then and daughters of Cain, as we have said, there were I born still worse children who became mighty hunters, violent and most fierce men who were termed giants by reason of the size of their bodies and their cruelty and wickedness. For these first began to harass their neighbours and to practise pillaging among men, getting their living rather by rapine than by being contented with the sweat and labour of toil, and their wickedness increased to such a pitch that the world could only be purified by the flood and deluge.”

“Now this is the first lust which conquered the world, and because of it the first transgression of the law took place. And in its train the children of Seth also came to fornication, so that they were rejected from the household of God thereby. For the lust of the belly is the captain of the host of the left side, and to it are fettered all the hosts of sin; and as captains of hosts go forth to war at the head of their companies against the enemy, even so also doth it, as the captain of the host of all wickedness, go forth to war against that which is good.”

בני האלהים THE SONS OF ELOHIM — The sons of princes and rulers (Genesis Rabbah 26:15). Another explanation of בני האלהים is that these were princely angels who came as messengers from God: they, too, intermingled with them (the daughters of men). Wherever the word אלהים occurs in the Scriptures it signifies authority, and the following passages prove this: (Exodus 4:16) “and thou shalt be his (אלהים) master”, and (Exodus 7:1) “See, I have made the (אלהים) a master.” כי טבת הנה THAT THEY WERE FAIR — Rabbi Judan said, “It is written here טבת, for when they were being made to appear “good” by being decked out to be taken beneath the marriage canopy one of the lords would come and carry her off first (Genesis Rabbah 26:5). מכל אשר בחרו OF ALL WHOM THEY CHOOSE — even if it were a married woman or a man or an animal (Genesis Rabbah 26:5).”

“BNEI HA’ELOHIM. The sons of princes and rulers. This is the language of Rashi, and so it is in Bereshith Rabbah. If so, Scripture relates that the judges whose duty it was to administer justice among them committed open violence without anyone interfering. ‘KI’ (WHEN) THEY WERE FAIR. [The meaning of the word ki here] is the same as in the verses: ‘Ki’ (when) thou seest the ass of him that hateth thee; ‘ki’ (when) a bird’s nest chance to be before thee. When the daughters of men were fair, they would take them forcibly as wives for themselves. Thus Scripture tells of the violence and mentions further, whomsoever they chose, in order to include those who were married to others. Scripture, however, did not mention the prohibition concerning them clearly, and the punishment decreed upon them was only because of the violence, because this is a reasoned concept and does not require the Torah to prohibit it.”

Or "good" (k), not in a moral but natural sense; goodly to look upon, of a beautiful aspect; and they looked upon, and only regarded their external beauty, and lusted after them: those "sons of God" were not angels either good or bad, as many have thought, since they are incorporeal beings, and cannot be affected with fleshly lusts, or marry and be given in marriage, or generate and be generated; nor the sons of judges, magistrates, and great personages, nor they themselves, as the Targums of Onkelos and Jonathan, and so Jarchi and Aben Ezra; but this could be no crime in them, to look upon and take in marriage such persons, though they were the daughters of the meaner sort; and supposing they acted a criminal part in looking at them, and lusting after them, and committing fornication with them, and even in marrying irreligious persons; yet this could only be a partial, not an universal corruption, as is after affirmed, though such examples must indeed have great influence upon the populace; but rather this is to be understood of the posterity of Seth, who from the times of Enos, when then began to be called by the name of the Lord, Gen 4:25 had the title of the sons of God, in distinction from the children of men; these claimed the privilege of divine adoption, and professed to be born of God, and partakers of his grace, and pretended to worship him according to his will, so far as revealed to them, and to fear and serve and glorify him. According to the Arabic writers (l), immediately after the death of Adam the family of Seth was separated from the family of Cain; Seth took his sons and their wives to a high mountain (Hermon), on the top of which Adam was buried, and Cain and all his sons lived in the valley beneath, where Abel was slain; and they on the mountain obtained a name for holiness and purity, and were so near the angels that they could hear their voices and join their hymns with them; and they, their wives and their children, went by the common name of the sons of God: and now these were adjured, by Seth and by succeeding patriarchs, by no means to go down from the mountain and join the Cainites; but notwithstanding in the times of Jared some did go down, it seems; See Gill on Gen 5:20 and after that others, and at this time it became general; and being taken with the beauty of the daughters of Cain and his posterity, they did as follows: and they took them wives of all that they chose; not by force, as Aben Ezra and Ben Gersom interpret, for the Cainites being more numerous and powerful than they, it can hardly be thought that the one would attempt it, or the other suffer it; but they intermarried with them, which the Cainites might not be averse unto; they took to them wives as they fancied, which were pleasing to the flesh, without regard to their moral and civil character, and without the advice and consent of their parents, and without consulting God and his will in the matter; or they took women as they pleased, and were to their liking, and committed fornication, to which the Cainites were addicted; for they spent their time in singing and dancing, and in uncleanness, whereby the posterity of Seth or sons of God were allured to come down and join them, and commit fornication with them, as the Arabic writers (m) relate.

“The sons of God. The descendants of Seth and Enos are here called Sons of God, from their religion and piety: whereas the ungodly race of Cain, who by their carnal affections lay grovelling upon the earth, are called the children of men. The unhappy consequence of the former marrying with the latter, ought to be a warning to Christians to be very circumspect in their marriages; and not to suffer themselves to be determined in choice by their carnal passion, to the prejudice of virtue or religion. (Challoner) — See St. Chrysostom, hom. 22, &c. Some copies of the Septuagint having the angels of God, induced some of the ancients to suppose, that these spiritual beings (to whom, by another mistake, they attributed a sort of aerial bodies) had commerce with women, as the pagans derived their heroes from a mortal and a god. But this notion, which is borrowed from the book of Henoch, is quite exploded. (Calmet) — The distinction of the true Church from the synagogue of satan, here established, has been ever since retained, as heretics are still distinguished from Catholics. (Worthington) (St. Augustine)”

“And it came to pass when the children of men had multiplied that in those days were born unto them beautiful and comely daughters. And the angels, the children of the heaven, saw and lusted after them, and said to one another: 'Come, let us choose us wives from among the children of men and beget us children.' And Semjaza, who was their leader, said unto them: 'I fear ye will not indeed agree to do this deed, and I alone shall have to pay the penalty of a great sin.' And they all answered him and said: 'Let us all swear an oath, and all bind ourselves by mutual imprecations not to abandon this plan but to do this thing.' Then sware they all together and bound themselves by mutual imprecations upon it. And they were in all two hundred; who descended in the days of Jared on the summit of Mount Hermon, and they called it Mount Hermon, because they had sworn and bound themselves by mutual imprecations upon it. And these are the names of their leaders: Samlazaz, their leader, Araklba, Rameel, Kokablel, Tamlel, Ramlel, Danel, Ezeqeel, Baraqijal, Asael, Armaros, Batarel, Ananel, Zaqiel, Samsapeel, Satarel, Turel, Jomjael, Sariel. These are their chiefs of tens. And all the others together with them took unto themselves wives, and each chose for himself one, and they began to go in unto them and to defile themselves with them, and they taught them charms and enchantments, and the cutting of roots, and made them acquainted with plants. And they became pregnant, and they bare great giants, whose height was three thousand ells: Who consumed all the acquisitions of men. And when men could no longer sustain them, the giants turned against them and devoured mankind. And they began to sin against birds, and beasts, and reptiles, and fish, and to devour one another's flesh, and drink the blood. Then the earth laid accusation against the lawless ones. And Azazel taught men to make swords, and knives, and shields, and breastplates, and made known to them the metals of the earth and the art of working them, and bracelets, and ornaments, and the use of antimony, and the beautifying of the eyelids, and all kinds of costly stones, and all colouring tinctures. And there arose much godlessness, and they committed fornication, and they were led astray, and became corrupt in all their ways. Semjaza taught enchantments, and root-cuttings, 'Armaros the resolving of enchantments, Baraqijal (taught) astrology, Kokabel the constellations, Ezeqeel the knowledge of the clouds, Araqiel the signs of the earth, Shamsiel the signs of the sun, and Sariel the course of the moon. And as men perished, they cried, and their cry went up to heaven... And He answered and said to me, and I heard His voice: 'Fear not, Enoch, thou righteous man and scribe of righteousness: approach hither and hear my voice. And go, say to the Watchers of heaven, who have sent thee to intercede for them: "You should intercede" for men, and not men for you: Wherefore have ye left the high, holy, and eternal heaven, and lain with women, and defiled yourselves with the daughters of men and taken to yourselves wives, and done like the children of earth, and begotten giants (as your) sons? And though ye were holy, spiritual, living the eternal life, you have defiled yourselves with the blood of women, and have begotten (children) with the blood of flesh, and, as the children of men, have lusted after flesh and blood as those also do who die and perish. Therefore have I given them wives also that they might impregnate them, and beget children by them, that thus nothing might be wanting to them on earth. But you were formerly spiritual, living the eternal life, and immortal for all generations of the world. And therefore I have not appointed wives for you; for as for the spiritual ones of the heaven, in heaven is their dwelling. And now, the giants, who are produced from the spirits and flesh, shall be called evil spirits upon the earth, and on the earth shall be their dwelling. Evil spirits have proceeded from their bodies; because they are born from men and from the holy Watchers is their beginning and primal origin; they shall be evil spirits on earth, and evil spirits shall they be called. [As for the spirits of heaven, in heaven shall be their dwelling, but as for the spirits of the earth which were born upon the earth, on the earth shall be their dwelling.] And the spirits of the giants afflict, oppress, destroy, attack, do battle, and work destruction on the earth, and cause trouble: they take no food, but nevertheless hunger and thirst, and cause offences. And these spirits shall rise up against the children of men and against the women, because they have proceeded from them... From the days of the slaughter and destruction and death of the giants, from the souls of whose flesh the spirits, having gone forth, shall destroy without incurring judgement -thus shall they destroy until the day of the consummation, the great judgement in which the age shall be consummated, over the Watchers and the godless, yea, shall be wholly consummated." And now as to the watchers who have sent thee to intercede for them, who had been aforetime in heaven, (say to them): "You have been in heaven, but all the mysteries had not yet been revealed to you, and you knew worthless ones, and these in the hardness of your hearts you have made known to the women, and through these mysteries women and men work much evil on earth." Say to them therefore: " You have no peace."'”
