He said: I will destroy man, whom I have created, from the face of the earth, from man even to beasts, from the creeping thing even to the fowls of the air, for it repenteth me that I have made them.

“(94) Why God, after having threatened to destroy mankind, says that he will also destroy all the beasts likewise; using the expression, "from man to beast, and from creeping things to flying creatures;" for how could irrational animals have committed sin? (#Ge 6:7). This is the literal statement of the holy scripture, and it informs us that animals were not necessarily and in their primary cause created for their own sake, but for the sake of mankind and to act as the servants of men; and when the men were destroyed, it followed necessarily and naturally that they also should be destroyed with them, as soon as the men, for whose sake they had been made, had ceased to exist. But as to the hidden meaning conveyed by the statement, since man is a symbol for the intellect which exists in us, and animals for the outward sense, when the chief creature has first been depraved and corrupted by wickedness, all the outward sense also perishes with him, because he had no relics whatever of virtue, which is the cause of salvation.”

“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."”

“When God announces the death of all animals on the earth and in the air, the intention is to declare the magnitude of the coming disaster. There is no question here of punishing with death irrational animals as though they were guilty of sin.”

ויאמר ה' אמחה את האדם AND GOD SAID I WILL BLOT OUT THE MAN — He is dust and I shall bring water upon him and blot him out: that is why this root מחה is used (it expresses the idea of sponging out by means of wet or dampness) (Genesis Rabbah 28:2). מאדם ועד בהמה — FROM MAN, TO BEAST — These also corrupted their way (Genesis Rabbah 28:8). Another explanation is: All things were created on man’s account; when he ceases to be, what need of them? (Sanhedrin 108a) כי נחמתי כי עשיתים means for I have thought out what to do because I have made them. (Cf. this with Rashi’s second explanation of וינחם 5:6).”

“And the Lord said,.... Not to the angels, nor to Noah, but within himself, on observing to what a height the sin of man had got, and what a spread it made on the earth: I will destroy man, whom I have created, from the face of the earth; though he is my creature, the work of my hands, I have made him out of the earth, and made him lord of it; I am now determined to show my detestation of his wickedness, and for the honour of my justice to destroy him from off it; just as a potter takes a vessel he dislikes, when he has made it, and dashes it to pieces: or "I will wipe men off of the earth" (s); like so much dust; man was made of the dust of the earth, he is dust, yea, sinful dust and ashes; and God resolved to send a flood of waters on the earth, which should wash off man from it, like so much dust upon it, just as dust is carried off by a flood of water, see Kg2 21:13 or "I will blot out man" (t), as most render the words; that is, out of the book of the living, he shall no longer live upon the earth; out of the book of creation, or of the creatures, he shall have no more a being, or be seen among them, any more than what is blotted out of a book: both man and beast; or "from man to beast" (u); even every living creature upon the earth, from man to beast, one as well as another, and one for the sake of the other, the beasts for the sake of man; these were made for his use and benefit, but he sinning against God, and abusing his mercies, they are to be taken away, and destroyed for his sake, and as a punishment for his sins: and the creeping things, and the fowls of the air; not the creeping things in the great and wide sea, for the fishes died not in the deluge, but the creeping things on the earth, Gen 6:20. for it repenteth me that I have made them; man, male and female, whom he created; Adam and Eve, and their posterity, and particularly the present inhabitants of the earth: but though it may respect men principally, yet is not to be restrained to them, but takes in all the creatures before mentioned, made for the use of man; and the ends not being answered by them, God repented that he had made them, as well as man. Some think the repentance, attributed to God in this and the preceding verse, is not to be understood of him in himself, but of his Spirit in good men, particularly Noah, producing grief, sorrow, and repentance in him, who wished that man had never been, than to be so wicked as he was; but for such a sense there seems to be no manner of foundation in the text.

“And then Michael, Uriel, Raphael, and Gabriel looked down from heaven and saw much blood being shed upon the earth, and all lawlessness being wrought upon the earth. And they said one to another: 'The earth made without inhabitant cries the voice of their cryingst up to the gates of heaven. And now to you, the holy ones of heaven, the souls of men make their suit, saying, "Bring our cause before the Most High."' And they said to the Lord of the ages: 'Lord of lords, God of gods, King of kings, and God of the ages, the throne of Thy glory (standeth) unto all the generations of the ages, and Thy name holy and glorious and blessed unto all the ages! Thou hast made all things, and power over all things hast Thou: and all things are naked and open in Thy sight, and Thou seest all things, and nothing can hide itself from Thee. Thou seest what Azazel hath done, who hath taught all unrighteousness on earth and revealed the eternal secrets which were (preserved) in heaven, which men were striving to learn: And Semjaza, to whom Thou hast given authority to bear rule over his associates. And they have gone to the daughters of men upon the earth, and have slept with the women, and have defiled themselves, and revealed to them all kinds of sins. And the women have borne giants, and the whole earth has thereby been filled with blood and unrighteousness. And now, behold, the souls of those who have died are crying and making their suit to the gates of heaven, and their lamentations have ascended: and cannot cease because of the lawless deeds which are wrought on the earth. And Thou knowest all things before they come to pass, and Thou seest these things and Thou dost suffer them, and Thou dost not say to us what we are to do to them in regard to these.' Then said the Most High, the Holy and Great One spake, and sent Uriel to the son of Lamech, and said to him: 'Go to Noah and tell him in my name "Hide thyself!" and reveal to him the end that is approaching: that the whole earth will be destroyed, and a deluge is about to come upon the whole earth, and will destroy all that is on it. And now instruct him that he may escape and his seed may be preserved for all the generations of the world.' And again the Lord said to Raphael: 'Bind Azazel hand and foot, and cast him into the darkness: and make an opening in the desert, which is in Dudael, and cast him therein. And place upon him rough and jagged rocks, and cover him with darkness, and let him abide there for ever, and cover his face that he may, not see light. And on the day of the great judgement he shall be cast into the fire. And heal the earth which the angels have corrupted, and proclaim the healing of the earth, that they may heal the plague, and that all the children of men may not perish through all the secret things that the Watchers have disclosed and have taught their sons. And the whole earth has been corrupted through the works that were taught by Azazel: to him ascribe all sin.' And to Gabriel said the Lord: 'Proceed against the bastards and the reprobates, and against the children of fornication: and destroy [the children of fornication and] the children of the Watchers from amongst men [and cause them to go forth]: send them one against the other that they may destroy each other in battle: for length of days shall they not have. And no request that they (i.e. their fathers) make of thee shall be granted unto their fathers on their behalf; for they hope to live an eternal life, and that each one of them will live five hundred years.' And the Lord said unto Michael: 'Go, bind Semjaza and his associates who have united themselves with women so as to have defiled themselves with them in all their uncleanness. And when their sons have slain one another, and they have seen the destruction of their beloved ones, bind them fast for seventy generations in the valleys of the earth, till the day of their judgement and of their consummation, till the judgement that is for ever and ever is consummated. In those days they shall be led off to the abyss of fire: and to the torment and the prison in which they shall be confined for ever. And whosoever shall be condemned and destroyed will from thenceforth be bound together with them to the end of all generations. And destroy all the spirits of the reprobate and the children of the Watchers, because they have wronged mankind. Destroy all wrong from the face of the earth and let every evil work come to an end: and let the plant of righteousness and truth appear: and it shall prove a blessing; the works of righteousness and truth' shall be planted in truth and joy for evermore. And then shall all the righteous escape, And shall live till they beget thousands of children And all the days of their youth and their old age Shall they complete in peace. And then shall the whole earth be tilled in righteousness, and shall all be planted with trees and be full of blessing. And all desirable trees shall be planted on it, and they shall plant vines on it: and the vine which they plant thereon shall yield wine in abundance, and as for all the seed which is sown thereon each measure (of it) shall bear a thousand, and each measure of olives shall yield ten presses of oil. And cleanse thou the earth from all oppression, and from all unrighteousness, and from all sin, and from all godlessness: and all the uncleanness that is wrought upon the earth destroy from off the earth. And all the children of men shall become righteous, and all nations shall offer adoration and shall praise Me, and all shall worship Me. And the earth shall be cleansed from all defilement, and from all sin, and from all punishment, and from all torment, and I will never again send (them) upon it from generation to generation and for ever. And in those days I will open the store chambers of blessing which are in the heaven, so as to send them down upon the earth over the work and labour of the children of men. And truth and peace shall be associated together throughout all the days of the world and throughout all the generations of men.'”
