Genesis 11:2-4

2And as people journeyed eastward,1 they found a plain in the land of Shinar2 and settled there.

3And they said to one another, “Come, let us make bricks and bake them thoroughly.” So they used brick instead of stone, and tar instead of mortar.

4“Come,” they said, “let us build for ourselves a city with a tower that reaches to the heavens, that we may make a name for ourselves and not be scattered over the face of all the earth.”
