Genesis 11:2-4

2When they traveled eastward, they found a valley-plain in the land of Shinar and settled there.

3They said to one another, “Come! Let’s make bricks and bake them until they’re hard.” So they used bricks for stone, and tar for mortar.

4Then they said, “Come! Let’s build ourselves a city, with a tower whose top reaches into heaven. So let’s make a name for ourselves, or else we will be scattered over the face of the whole land.”
