And the Lord came down. The remaining part of the history now follows, in which Moses teaches us with what ease the Lord could overturn their insane attempts, and scatter abroad all their preparations. There is no doubt that they strenuously set about what they had presumptuously devised. But Moses first intimates that God, for a little while, seemed to take no notice of them, [1] in order that suddenly breaking off their work at its commencement, by the confusion of their tongues, he might give the more decisive evidence of his judgment. For he frequently bears with the wicked, to such an extent, that he not only suffers them to contrive many nefarious things, as if he were unconcerned, or were taking repose; but even further, their impious and perverse designs with animating success, in order that he may at length cast them down to a lower depth. The descent of God, which Moses here records, is spoken of in reference to men rather than to God; who, as we know, does not move from place to place. But he intimates that God gradually and as with a tardy step, appeared in the character of an Avenger. The Lord therefore descended that he might see; that is, he evidently showed that he was not ignorant of the attempt which the Babylonians were making.

And the Lord came down - A lesson, says an ancient Jewish commentator, to magistrates to examine every evidence before they decree judgment and execute justice.

And the LORD (f) came down to see the city and the tower, which the children of men builded.
(f) Meaning, that he declared by effect, that he knew their wicked enterprise; for God's power is everywhere, and neither ascends nor descends.

And the Lord came down to see the city and the tower,.... Not locally or visibly, being immense, omnipresent, and invisible; nor in order to see and take notice of what he otherwise could not see from heaven, for he is omniscient; but this is spoken after the manner of men, and is to be understood of some effects and displays of his power, which were manifest, and showed him to be present: the Targum is,"and the Lord was revealed to take vengeance on them on account of the business of the city and tower the children of men built.''This shows the patience and longsuffering of God, that he did not immediately proceed against them, and his wisdom and justice in taking cognizance of the affair, and inquiring into it; examining the truth and reality of things before he passed judgment and took measures to hinder them in the execution of their design; all which must be understood agreeably to the divine Majesty, and as accommodated to the capacities of men, and as an instruction to them in judging matters they have a concern in:
which the children of men builded; or were building, for they had not finished their building, at least not the city, as appears from Genesis 11:8. These were either the whole body of the people, under the general appellation of "the children of men": or else a part of them, distinguished by this character from the "sons of God", who were truly religious; by which it seems that Noah, Shem, Arphaxad, Salah, and others, were not concerned in this affair, who though they might come with the rest unto Shinar, yet when they understood their design, refused to join with them in it; so that it was only the carnal and irreligious part of them, who very probably were by far the majority, and therefore there was no overruling their debates, and stopping them in their works, that were the builders; and these might be the posterity of Ham in general, with others of Shem and Japheth mixed with them. Josephus (g) makes Nimrod to be the head of them, which is not likely, as before observed.
(g) Antiqu. l. 1. c. 4. sect. 2, 3.

Here is an expression after the manner of men; The Lord came down to see the city. God is just and fair in all he does against sin and sinners, and condemns none unheard. Pious Eber is not found among this ungodly crew; for he and his are called the children of God; their souls joined not themselves to the assembly of these children of men. God suffered them to go on some way, that the works of their hands, from which they promised themselves lasting honour, might turn to their lasting reproach. God has wise and holy ends, in allowing the enemies of his glory to carry on their wicked projects a great way, and to prosper long. Observe the wisdom and mercy of God, in the methods taken for defeating this undertaking. And the mercy of God in not making the penalty equal to the offence; for he deals not with us according to our sins. The wisdom of God, in fixing upon a sure way to stop these proceedings. If they could not understand one another, they could not help one another; this would take them off from their building. God has various means, and effectual ones, to baffle and defeat the projects of proud men that set themselves against him, and particularly he divides them among themselves. Notwithstanding their union and obstinacy God was above them; for who ever hardened his heart against him, and prospered? Their language was confounded. We all suffer by it to this day: in all the pains and trouble used to learn the languages we have occasion for, we suffer for the rebellion of our ancestors at Babel. Nay, and those unhappy disputes, which are strifes of words, and arise from misunderstanding one another's words, for ought we know, are owing to this confusion of tongues. They left off to build the city. The confusion of their tongues not only unfitted them for helping one another, but they saw the hand of the Lord gone out against them. It is wisdom to leave off that which we see God fights against. God is able to blast and bring to nought all the devices and designs of Babel-builders: there is no wisdom nor counsel against the Lord. The builders departed according to their families, and the tongue they spake, to the countries and places allotted to them. The children of men never did, nor ever will, come all together again, till the great day, when the Son of man shall sit upon the throne of his glory, and all nations shall be gathered before him.

"Jehovah came down to see the city and the tower, which the children of men had built" (the perfect בּנוּ refers to the building as one finished up to a certain point). Jehovah's "coming down" is not the same here as in Exodus 19:20; Exodus 34:5; Numbers 11:25; Numbers 12:5, viz., the descent from heaven of some visible symbol of His presence, but is an anthropomorphic description of God's interposition in the actions of men, primarily a "judicial cognizance of the actual fact," and then, Genesis 11:7, a judicial infliction of punishment. The reason for the judgment is given in the word, i.e., the sentence, which Jehovah pronounces upon the undertaking (Genesis 11:6): "Behold one people (עם lit., union, connected whole, from עמם to bind) and one language have they all, and this (the building of this city and tower) is (only) the beginning of their deeds; and now (sc., when they have finished this) nothing will be impossible to them (מהם יבּצר לא lit., cut off from them, prevented) which they purpose to do" (יזמוּ for יזמּוּ from זמם, see Genesis 9:19). By the firm establishment of an ungodly unity, the wickedness and audacity of men would have led to fearful enterprises. But God determined, by confusing their language, to prevent the heightening of sin through ungodly association, and to frustrate their design. "Up" (הבה "go to," an ironical imitation of the same expression in Genesis 11:3 and Genesis 11:4), "We will go down, and there confound their language (on the plural, see Genesis 1:26; נבלה for נבלּה, Kal from בּלל, like יזמו in Genesis 1:6), that they may not understand one another's speech." The execution of this divine purpose is given in Genesis 11:8, in a description of its consequences: "Jehovah scattered them abroad from thence upon the face of all the earth, and they left off building the city." We must not conclude from this, however, that the differences in language were simply the result of the separation of the various tribes, and that the latter arose from discord and strife; in which case the confusion of tongues would be nothing more than "dissensio animorum, per quam factum sit, ut qui turrem struebant distracti sint in contraria studia et consilia" (Bitringa). Such a view not only does violence to the words "that one may not discern (understand) the lip (language) of the other," but is also at variance with the object of the narrative. When it is stated, first of all, that God resolved to destroy the unity of lips and words by a confusion of the lips, and then that He scattered the men abroad, this act of divine judgment cannot be understood in any other way, than that God deprived them of the ability to comprehend one another, and thus effected their dispersion. The event itself cannot have consisted merely in a change of the organs of speech, produced by the omnipotence of God, whereby speakers were turned into stammerers who were unintelligible to one another. This opinion, which is held by Bitringa and Hoffmann, is neither reconcilable with the text, nor tenable as a matter of fact. The differences, to which this event gave rise, consisted not merely in variations of sound, such as might be attributed to differences in the formation in the organs of speech (the lip or tongue), but had a much deeper foundation in the human mind. If language is the audible expression of emotions, conceptions, and thoughts of the mind, the cause of the confusion or division of the one human language into different national dialects must be sought in an effect produced upon the human mind, by which the original unity of emotion, conception, thought, and will was broken up. This inward unity had no doubt been already disturbed by sin, but the disturbance had not yet amounted to a perfect breach. This happened first of all in the event recorded here, through a direct manifestation of divine power, which caused the disturbance produced by sin in the unity of emotion, thought, and will to issue in a diversity of language, and thus by a miraculous suspension of mutual understanding frustrated the enterprise by which men hoped to render dispersion and estrangement impossible. More we cannot say in explanation of this miracle, which lies before us in the great multiplicity and variety of tongues, since even those languages which are genealogically related - for example, the Semitic and Indo-Germanic - were no longer intelligible to the same people even in the dim primeval age, whilst others are so fundamentally different from one another, that hardly a trace remains of their original unity. With the disappearance of unity the one original language was also lost, so that neither in the Hebrew nor in any other language of history has enough been preserved to enable us to form the least conception of its character.
(Note: The opinion of the Rabbins and earlier theologians, that the Hebrew was the primitive language, has been generally abandoned in consequence of modern philological researches. The fact that the biblical names handed down from the earliest times are of Hebrew extraction proves nothing. With the gradual development and change of language, the traditions with their names were cast into the mould of existing dialects, without thereby affecting the truth of the tradition. For as Drechster has said, "it makes no difference whether I say that Adam's eldest son had a name corresponding to the name Cain from קנה, or to the name Ctesias from κτᾶσθαι; the truth of the Thorah, which presents us with the tradition handed down from the sons of Noah through Shem to Abraham and Israel, is not a verbal, but a living tradition - is not in the letter, but in the spirit.")
The primitive language is extinct, buried in the materials of the languages of the nations, to rise again one day to eternal life in the glorified form of the καιναὶ γλῶσσαι intelligible to all the redeemed, when sin with its consequences is overcome and extinguished by the power of grace. A type of pledge of this hope was given in the gift of tongues on the outpouring of the Holy Spirit upon the Church on the first Christian day of Pentecost, when the apostles, filled with the Holy Ghost, spoke with other or new tongues of "the wonderful works of God," so that the people of every nation under heaven understood in their own language (Acts 2:1-11).
From the confusion of tongues the city received the name Babel (בּבל i.e., confusion, contracted from בּלבּל from בּלל to confuse), according to divine direction, though without any such intention on the part of those who first gave the name, as a standing memorial of the judgment of God which follows all the ungodly enterprises of the power of the world.
(Note: Such explanations of the name as "gate, or house, or fortress of Bel," are all the less worthy of notice, because the derivation ἀπὸ τοῦ Βήλου in the Etymol. magn., and in Persian and Nabatean works, is founded upon the myth, that Bel was the founder of the city. And as this myth is destitute of historical worth, so is also the legend that the city was built by Semiramis, which may possibly have so much of history as its basis, that this half-mythical queen extended and beautified the city, just as Nebuchadnezzar added a new quarter, and a second fortress, and strongly fortified it.)
Of this city considerable ruins still remain, including the remains of an enormous tower, Birs Nimrud, which is regarded by the Arabs as the tower of Babel that was destroyed by fire from heaven. Whether these ruins have any historical connection with the tower of the confusion of tongues, must remain, at least for the present, a matter of uncertainty. With regard to the date of the event, we find from Genesis 11:10 that the division of the human race occurred in the days of Peleg, who was born 100 years after the flood. In 150 or 180 years, with a rapid succession of births, the descendants of the three sons of Noah, who were already 100 years old and married at the time of the flood, might have become quite numerous enough to proceed to the erection of such a building. If we reckon, for example, only four male and four female births as the average number to each marriage, since it is evident from Genesis 11:12. that children were born as early as the 30th or 35th year of their parent's age, the sixth generation would be born by 150 years after the flood, and the human race would number 12,288 males and as many females. Consequently there would be at least about 30,000 people in the world at this time.

And the Lord came down to see the city - 'Tis an expression after the manner of men, he knew it as clearly as men know that which they come upon the place to view. And the tower which the children of men builded - Which speaks, Their weakness and frailty, it was a foolish thing for the children of men, worms of the earth, to defy heaven. Their sinfulness, they were the sons of Adam, so it is in the Hebrew; nay, of that Adam, that sinful disobedient Adam, whose children are by nature children of disobedience. Their distinction from the children of God, from whom those daring builders had separated themselves, and built this tower to support and perpetuate the separation.
