Genesis 11:1-5

1And the whole earth was of one language, and of one speech.12 2And it came to pass, as they journeyed from the east, that they found a plain in the land of Shinar; and they dwelt there.3 3And they said one to another, come, let us make brick, and burn them thoroughly. And they had brick for stone, and slime had they for mortar.45 4And they said, come, let us build us a city and a tower, whose top may reach to heaven; and let us make us a name, lest we should be scattered abroad upon the face of the whole earth.

5And the LORD came down to see the city and the tower, which the children of men were building.
