Genesis 11:4-6

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.”

11:5 But the Lord came down to see the city and the tower that the people had started building. 11:6 And the Lord said, “If as one people all sharing a common language they have begun to do this, then nothing they plan to do will be beyond them.
