Genesis 11:4-6 NIV

[4] Then 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.” [5] But the LORD came down to see the city and the tower the people were building. [6] The 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.
