Genesis 11:4-7

They said, “Come, let us build for ourselves a city, and a tower whose top will reach into heaven, and let us make for ourselves a name, otherwise we will be scattered abroad over the face of the whole earth.” The LORD came down to see the city and the tower which the sons of men had built. The LORD said, “Behold, they are one people, and they all have the same language. And this is what they began to do, and now nothing which they purpose to do will be impossible for them. Come, let Us go down and there confuse their language, so that they will not understand one another’s speech.”
