Genesis 11:3-4, 7

They said to each other, “Let’s make bricks and bake them to make them hard.” So they used bricks instead of stones, and tar instead of mortar. Then they said to each other, “Let’s build a city and a tower for ourselves, whose top will reach high into the sky. We will become famous. Then we will not be scattered over all the earth.”

Come, let us go down and confuse their language so they will not be able to understand each other.”
