Genesis 11:3-5

Darby Translation

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.

⁴ And they said, Come on, let us build ourselves a city and a tower, the top of which [may reach] to the heavens; and let us make ourselves a name, lest we be scattered over the face of the whole earth.

⁵ And Jehovah came down to see the city and the tower which the children of men built.
