Genesis 11:3

Let - To hinder or obstruct.

Let us make brick - It appears they were obliged to make use of brick, as there was an utter scarcity of stones in that district; and on the same account they were obliged to use slime, that is, bitumen, (Vulg). ασφαλτος, (Septuagint) for mortar: so it appears they had neither common stone nor lime-stone; hence they had brick for stone, and asphaltus or bitumen instead of mortar.

A building is to be erected of brick and asphalt. The Babylonian soil is still celebrated for these architectural materials. There is here a fine clay, mingled with sand, forming the very best material for brick, while stones are not to be found at a convenient distance. Asphalt is found boiling up from the soil in the neighborhood of Babylon and of the Dead Sea, which is hence called the "lacus Asphaltites." The asphalt springs of Is or Hit on the Euphrates are celebrated by many writers. "Burn them thoroughly." Sun-dried bricks are very much used in the East for building purposes. These, however, were to be burned, and thereby rendered more durable. "Brick for stone." This indicates a writer belonging to a country and an age in which stone buildings were familiar, and therefore not to Babylonia. Brickmaking was well known to Moses in Egypt; but this country also abounds in quarries and splendid erections of stone, and the Sinaitic peninsula is a mass of granitic hills. The Shemites mostly inhabited countries abounding in stone. "Asphalt for mortar." Asphalt is a mineral pitch. The word rendered mortar means at first clay, and then any kind of cement.

11:3 Go to, let us make brick, let us build us a city - The country being a plain, yielded neither stone nor morter, yet that did not discourage them, but they made brick to serve instead of stone, and slime, or pitch, instead of morter. Some think they intended hereby to secure themselves against the waters of another flood, but if they had, they would have chosen to build upon a mountain rather than upon a plain. But two things it seems they aimed at in building. To make them a name: they would do something to be talked of by posterity. But they could not gain this point; for we do not find in any history the name of so much as one of these Babel - builders. Philo Judeus saith they engraved every one his name upon a brick; yet neither did that serve their purpose. They did it to prevent their dispersion; lest we be scattered abroad upon the face of the earth - It was done (saith Josephus) in disobedience to that command, Gen 9:1, replenish the earth. God orders them to scatter. No, say they, we will live and die together. In order hereunto they engage themselves and one another in this vast undertaking. That they might unite in one glorious empire, they resolve to build this city and tower, to be the metropolis of their kingdom, and the center of their unity.
