Genesis 11:2-4

2As people moved eastward, Or from the east; or in the east they found a plain in Shinar That is, Babylonia and settled there. 3They said to each other, “Come, let’s make bricks and bake them thoroughly.” They used brick instead of stone, and tar for mortar.

4Then they said, “Come, let us build ourselves a city, with a tower that reaches to the heavens, so that we may make a name for ourselves; otherwise we will be scattered over the face of the whole earth.”
