“1. Now the sons of Noah were three, - Shem, Japhet, and Ham, born one hundred years before the Deluge. These first of all descended from the mountains into the plains, and fixed their habitation there; and persuaded others who were greatly afraid of the lower grounds on account of the flood, and so were very loath to come down from the higher places, to venture to follow their examples. Now the plain in which they first dwelt was called Shinar. God also commanded them to send colonies abroad, for the thorough peopling of the earth, that they might not raise seditions among themselves, but might cultivate a great part of the earth, and enjoy its fruits after a plentiful manner. But they were so ill instructed that they did not obey God; for which reason they fell into calamities, and were made sensible, by experience, of what sin they had been guilty: for when they flourished with a numerous youth, God admonished them again to send out colonies; but they, imagining the prosperity they enjoyed was not derived from the favor of God, but supposing that their own power was the proper cause of the plentiful condition they were in, did not obey him. Nay, they added to this their disobedience to the Divine will, the suspicion that they were therefore ordered to send out separate colonies, that, being divided asunder, they might the more easily be Oppressed. 2. Now it was Nimrod who excited them to such an affront and contempt of God. He was the grandson of Ham, the son of Noah, a bold man, and of great strength of hand. He persuaded them not to ascribe it to God, as if it was through his means they were happy, but to believe that it was their own courage which procured that happiness. He also gradually changed the government into tyranny, seeing no other way of turning men from the fear of God, but to bring them into a constant dependence on his power. He also said he would be revenged on God, if he should have a mind to drown the world again; for that he would build a tower too high for the waters to be able to reach! and that he would avenge himself on God for destroying their forefathers! 3. Now the multitude were very ready to follow the determination of Nimrod, and to esteem it a piece of cowardice to submit to God; and they built a tower, neither sparing any pains, nor being in any degree negligent about the work: and, by reason of the multitude of hands employed in it, it grew very high, sooner than any one could expect; but the thickness of it was so great, and it was so strongly built, that thereby its great height seemed, upon the view, to be less than it really was. It was built of burnt brick, cemented together with mortar, made of bitumen, that it might not be liable to admit water. When God saw that they acted so madly, he did not resolve to destroy them utterly, since they were not grown wiser by the destruction of the former sinners; but he caused a tumult among them, by producing in them diverse languages, and causing that, through the multitude of those languages, they should not be able to understand one another. The place wherein they built the tower is now called Babylon, because of the confusion of that language which they readily understood before; for the Hebrews mean by the word Babel, confusion. The Sibyl also makes mention of this tower, and of the confusion of the language, when she says thus: "When all men were of one language, some of them built a high tower, as if they would thereby ascend up to heaven, but the gods sent storms of wind and overthrew the tower, and gave every one his peculiar language; and for this reason it was that the city was called Babylon." But as to the plan of Shinar, in the country of Babylonia, Hestiaeus mentions it, when he says thus: "Such of the priests as were saved, took the sacred vessels of Jupiter Enyalius, and came to Shinar of Babylonia."”

“And they arose and came from the land of the east; and, as they went through the land, they chanced upon the land of Shinar, which was exceeding broad; where they took in hand to build a tower. They sought means thereby to go up to heaven, and be able to leave their work as a memorial to those men who should come after them. And the building was made with burnt bricks and bitumen: and the boldness of their audacity went forward, as they were all of one mind and consent, and by means of one speech they served the purpose of their desires. But that the work should advance no further, God divided their tongues, that they should no longer be able to understand one another. And so they were scattered and planted out, and took possession of the world, and dwelt in groups and companies each according to his language: whence came the diverse tribes and various languages upon the earth. So then, whereas three races of men took possession of the earth, and one of them was under the curse, and two under the blessing, the blessing first of all came to Shem, whose race dwelt in the east and held the land of the Chaldeans.”

“AGAIN, whereas Moses wrote an account of the building of the tower, and how from one language men passed into the confusion of many dialects, the author just before mentioned, in his work entitled Of Assyrian History, bears the like testimony, speaking as follows: [ABYDENUS] 'But there are some who say that the men who first arose out of the earth, being puffed up by their strength and great stature, and proudly thinking that they were better than the gods, raised a huge tower, where Babylon now stands: and when they were already nearer to heaven, the winds came to the help of the gods, and overthrew their structure upon them, the ruins of which were called Babylon. And being up to that time of one tongue, they received from the gods a confused language; and afterwards war arose between Cronos and Titan. [JOSEPHUS] 'And the place in which they built the tower is now called Babylon, because of the confusion of what at first was clear in their language. For the Hebrews call confusion "Babel." '”

“And if any one cites the confusion of tongues that took place at the building of the tower, as contradicting what I have said, not even there is God spoken of as creating men's languages, but as confounding the existing one, that all might not hear all. For when all lived together and were not as yet divided by various differences of race, the aggregate of men dwelt together with one language among them; but when by the Divine will it was decreed that all the earth should be replenished by mankind, then, their community of tongue being broken up, men were dispersed in various directions and adopted this and that form of speech and language, possessing a certain bond of union in similarity of tongue, not indeed disagreeing from others in their knowledge of things, but differing in the character of their names. For a stone or a stick does not seem one thing to one man and another to another, but the different peoples call them by different names. So that our position remains unshaken, that human language is the invention of the human mind or understanding. For from the beginning, as long as all men had the same language, we see from Holy Scripture that men received no teaching of God's words, nor, when men were separated into various differences of language, did a Divine enactment prescribe how each man should talk. But God, willing that men should speak different languages, gave human nature full liberty to formulate arbitrary sounds, so as to render their meaning more intelligible. Accordingly, Moses, who lived many generations after the building of the tower, uses one of the subsequent languages in his historical narrative of the creation, and attributes certain words to God, relating these things in his own tongue in which he had been brought up, and with which he was familiar, not changing the names for God by foreign peculiarities and turns of speech, in order by the strangeness and novelty of the expressions to prove them the words of God Himself.”

“"When they traveled from the east, they found open country in the land of Sennar [Shinar] and settled there." Notice how the human race, instead of managing to keep to its own boundaries, always longs for more and reaches out for greater things. This is what the human race has lost in particular, not being prepared to recognize the limitations of its own condition but always lusting after more, entertaining ambitions beyond its capacity. In this regard, too, when people who chase after the things of the world acquire for themselves much wealth and status, they lose sight of their own nature, as it were, and aspire to such heights that they topple into the very depths. You could see this happening every day without others being any the wiser from the sight of it. Instead, they pause for a while but immediately lose all recollection of it and take the same road as the others and fall over the same precipice. This is exactly what you can see happening to these people in the present instance: "When they traveled from the east, they found open country in the land of Sennar [Shinar] and settled there." See how in gradual stages it teaches us the instability of their attitude. When they saw the open country (the text says), they packed up and left their previous dwelling and settled down there.”

“AS THEY JOURNEYED FROM THE EAST. Rashi comments: “They journeyed from where they were then dwelling, as it is written above, And their dwelling was from Mesha, as thou goest toward Sephar, unto the mountain of the east. From there they journeyed to search out for themselves a place that would accomodate them all, but they found none except Shinar.” But this is not correct for this is the account of the children of Shem only, concerning whom it was so said [that they dwelled at “the mountain of the east”], and why should Scripture attribute the dispersion to the descendants of Shem when the children of Japheth and of Ham were more numerous than they? Besides, their habitation in their countries was from Mesha to the mountain of the east, and the dispersion of the nations took place before they settled there, for the children of Japheth surely did not come from the isles of the sea, Verse 5. to the land of Shinar; rather, it was during the dispersion that G-d scattered them abroad upon the face of all the earth, and at that time they were settled in their lands, after their nations. And Rabbi Abraham ibn Ezra explained that the mountains of Ararat are in the east. [Thus the verse before us which states, as they journeyed from the east, means as they journeyed from the mountains of Ararat.] That which he said is correct for the mountains of Ararat are in the east near Assyria, as it is said, And they escaped into the land of Ararat. And when Noah came down from the mountain [upon which the ark had rested], he and his sons settled in those lands, and when they increased they journeyed from there to this valley called Shinar. According to our Rabbis, the men of the dispersion rebelled against their Creator. But those who pursue the plain meaning of Scripture say that their idea was only to be closely united, for Scripture declares their intention, lest we be scattered, and does not relate any other matter [motive] concerning them. But if it be as those commentators say, then the men of the dispersion were fools for how could one city and one tower suffice for all people of the world? Or perhaps they thought that they would not be fruitful and multiply, as it is written, and the seed of the wicked will be cut off. However, he who knows the meaning of the word “name” — as they said, and we will make for us a name — will understand their intent and will know the extent of their evil intention in constructing the tower. And then he will understand the whole subject, namely, that theirs was an evil thought, and the punishment that came over them — to be dispersed in their languages and countries — was meted out measure for measure for “they mutilated the shoots” [of faith by seeking to undermine the principle of the Unity]. Thus their sin was comparable to that of their father Adam. Perhaps on account of this the Sages expounded: “And the Eternal came down to see… which the children of men had built. Said Rabbi Berachyah, ‘[Whose children could they have been but the children of men?] Perhaps the children of donkeys or camels? Rather it means the children of the first man, etc.’” Contemplate further that in the entire subject of the flood, Scripture mentions Elokim (G-d), while in the entire matter of the dispersion it mentions the Tetragrammaton; the flood came on account of the corruption of the land, and the dispersion came because “they mutilated the shoots” of faith and therefore their punishment was meted out by His Great Name. This explains the “coming down” and also the Divine measure meted out in Sodom. The student learned [in the mystic lore of the Cabala] will understand.”

“And it came to pass, as they journeyed from the east,.... That is, the inhabitants of the whole earth; not Ham and his posterity only, or Nimrod and his company; but as all the sons of Noah and his posterity for a while dwelt together, or at least very near each other, and finding the place where they were too scanty for them, as their several families increased, they set out in a body from the place where they were, to seek for a more convenient one: it seems a little difficult how to interpret this phrase, "from the east", since if they came from Ararat in Armenia, where the ark rested, as that lay north of Shinar or Babylon, they might rather be said to come from the north than from the east, and rather came to it than from it: so some think the phrase should be rendered, "to the east" (b), or eastward, as in Gen 13:11. Jarchi thinks this refers to Gen 10:30 "and their dwelling was", &c. at "the mountain of the east"; from whence he supposes they journeyed, to find out a place that would hold them all, but could find none but Shinar; but then this restrains it to Joktan's sons, and besides, their dwelling there was not until after the confusion and dispersion. But it is very probable the case was this, that when Noah and his sons came out of the ark, in a little time they betook themselves to their former habitation, from whence they had entered into the ark, namely, to the east of the garden of Eden, where was the appearance of the divine Presence, or Shechinah; and from hence it was that these now journeyed: and so it was as they were passing on: that they found a plain in the land of Shinar; which the Targum of Jonathan paraphrases the land of Babylon; and Hestiaeus (c), a Phoenician historian, calls it Sennaar of Babylon; there are plain traces of this name in the Singara of Ptolemy (d) and Pliny (e), the Hebrew letter being sometimes pronounced as "G", as in Gaza and Gomorrah; the first of these place a city of this name in Mesopotamia, near the Tigris, and that of the other is reckoned a capital of the Rhetavi, a tribe of the Arabs, near Mesopotamia. This plain was very large, fruitful, and delightful, and therefore judged a fit place for a settlement, where they might have room enough, and which promised them a sufficient sustenance: and they dwelt there; and provided for their continuance, quickly beginning to build a city and tower, afterwards called Babylon: and that Babylon was built in a large plain is not only here asserted, but is confirmed by Herodotus (f), who says of it, that it lay , in a vast plain, and so Strabo (g); which was no other than the plain of Shinar.

“As they journeyed from the east - Assyria, Mesopotamia, and the country on the borders and beyond the Euphrates, are called the east in the sacred writings. Balaam said that the king of Moab had brought him from the mountains of the east, Num 23:7. Now it appears, from Num 22:5, that Balaam dwelt at Pethor, on the river Euphrates. And it is very probable that it was from this country that the wise men came to adore Christ; for it is said they came from the east to Jerusalem, Mat 2:1. Abraham is said to have come from the east to Canaan, Isa 41:2; but it is well known that he came from Mesopotamia and Chaldea. Isa 46:11, represents Cyrus as coming from the east against Babylon. And the same prophet represents the Syrians as dwelling eastward of Jerusalem, Isa 9:12 : The Syrians before, מקדם mikkedem, from the east, the same word which Moses uses here. Dan 11:44, represents Antiochus as troubled at news received from the east; i.e. of a revolt in the eastern provinces, beyond the Euphrates. Noah and his family, landing after the flood on one of the mountains of Armenia, would doubtless descend and cultivate the valleys: as they increased, they appear to have passed along the banks of the Euphrates, till, at the time specified here, they came to the plains of Shinar, allowed to be the most fertile country in the east. See Calmet. That Babel was built in the land of Shinar we have the authority of the sacred text to prove; and that Babylon was built in the same country we have the testimony of Eusebius, Praep. Evang., lib. ix., c. 15; and Josephus, Antiq., lib. i., c. 5.”

“As men multiplied they moved from the land of Ararat "eastward," or more strictly to the south-east, and settled in a plain. בּקעה does not denote a valley between mountain ranges, but a broad plain, πεδίον μέγα, as Herodotus calls the neighbourhood of Babylon. There they resolved to build an immense tower; and for this purpose they made bricks and burned them thoroughly (לשׂרפה "to burning" serves to intensify the verb like the inf. absol.), so that they became stone; whereas in the East ordinary buildings are constructed of bricks of clay, simply dried in the sun. For mortar they used asphalt, in which the neighbourhood of Babylon abounds. From this material, which may still be seen in the ruins of Babylon, they intended to build a city and a tower, whose top should be in heaven, i.e., reach to the sky, to make to themselves a name, that they might not be scattered over the whole earth. שׁם לו עשׂה denotes, here and everywhere else, to establish a name, or reputation, to set up a memorial (Isa 63:12, Isa 63:14; Jer 32:20, etc.). The real motive therefore was the desire for renown, and the object was to establish a noted central point, which might serve to maintain their unity. The one was just as ungodly as the other. For, according to the divine purpose, men were to fill the earth, i.e., to spread over the whole earth, not indeed to separate, but to maintain their inward unity notwithstanding their dispersion. But the fact that they were afraid of dispersion is a proof that the inward spiritual bond of unity and fellowship, not only "the oneness of their God and their worship," but also the unity of brotherly love, was already broken by sin. Consequently the undertaking, dictated by pride, to preserve and consolidate by outward means the unity which was inwardly lost, could not be successful, but could only bring down the judgment of dispersion.”
