Genesis 11:2

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 lo…

The old distinction between the sons of God and the sons of men (professors and profane) survived the flood, and now appeared again, when men began to multiply: according to this distinction we have, in this chapter, I. The dispersion of the sons of men at Babel (Gen 11:1-9), where we have, 1. Their presumptuous provoking design, which was to build a city and a tower (Gen 11:1-4). 2. The righteous judgment of God upon them in disappointing their design, by confounding their language, and so scattering them (Gen 11:5-9). II. The pedigree of the sons of God down to Abraham (v. 10-26), with a general account of his family, and removal out of his native country (Gen 11:27, etc.).

11:2 migrated to the east: See study note on 3:24. • Babylonia was located in southern Mesopotamia, the region of Nimrod’s later empire and city-building campaign (see 10:10; Isa 11:11; Dan 1:2; Zech 5:11).
