Genesis 11:3-4 ▼

3 and they each say to his neighbor, “Give help, let us make bricks, and burn [them] thoroughly”: and the brick is to them for stone, and the bitumen has been to them for mortar.

4 And they say, “Give help, let us build for ourselves a city and tower with its head in the heavens, and make for ourselves a name, lest we be scattered over the face of all the earth.”
