Genesis 11:4-6

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.”

5But the Lord came down to see the city and the tower the people were building.

6The Lord said, “If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them.
