Genesis 11:1-3

Darby Translation

11 And the whole earth had one language, and the same words.

² And it came to pass as they journeyed from the east, that they found a plain in the land of Shinar, and dwelt there.

³ And they said one to another, Come on, let us make bricks, and burn [them] thoroughly. And they had brick for stone, and they had asphalt for mortar.
