Genesis 11:2-4

11:2 When the people moved eastward, they found a plain in Shinar and settled there. 11:3 Then 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.) 11:4 Then 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.”
