Genesis 11:2-4

2When the people moved eastward, they found a plain in Shinar and settled there.

3Then they said to one another, “Come, let’s make bricks and bake them thoroughly.” (They had brick instead of stone and tar instead of mortar.)

4Then they said, “Come, let’s build ourselves a city and a tower with its top in the heavens so that we may make a name for ourselves. Otherwise we will be scattered across the face of the entire earth.”
