Genesis 11:3-5

Amplified Bible, Classic Edition

³ And they said one to another, Come, let us make bricks and burn them thoroughly. So they had brick for stone, and slime (bitumen) for mortar.

⁴ And they said, Come, let us build us a city and a tower whose top reaches into the sky, and let us make a name for ourselves, lest we be scattered over the whole earth.

⁵ And the Lord came down to see the city and the tower which the sons of men had built.
