Genesis 11:1-6
1. the whole earth was of one language. The descendants of Noah, united by the strong bond of a common language, had not separated, and notwithstanding the divine command to replenish the earth, were unwilling to separate. The more pious and well-disposed would of course obey the divine will; but a numerous body, seemingly the aggressive horde mentioned (Ge 10:10), determined to please themselves by occupying the fairest region they came to.
2. land of Shinar—The fertile valley watered by the Euphrates and Tigris was chosen as the center of their union and the seat of their power.
3. brick—There being no stone in that quarter, brick is, and was, the only material used for building, as appears in the mass of ruins which at the Birs Nimroud may have been the very town formed by those ancient rebels. Some of these are sun-dried—others burnt in the kiln and of different colors.
slime—bitumen, a mineral pitch, which, when hardened, forms a strong cement, commonly used in Assyria to this day, and forming the mortar found on the burnt brick remains of antiquity.4. a tower whose top may reach unto heaven—a common figurative expression for great height (De 1:28; 9:1-6).
lest we be scattered—To build a city and a town was no crime; but to do this to defeat the counsels of heaven by attempting to prevent emigration was foolish, wicked, and justly offensive to God.6. and now nothing will be restrained from them—an apparent admission that the design was practicable, and would have been executed but for the divine interposition.
