Genesis 11:4-9 (NKJV)
And they said, "Come, let us build ourselves a city, and a tower whose top is in the heavens; let us make a name for ourselves, lest we be scattered abroad over the face of the whole earth."
But the LORD came down to see the city and the tower which the sons of men had built.
Come, let Us go down and there confuse their language, that they may not understand one another's speech."
So the LORD scattered them abroad from there over the face of all the earth, and they ceased building the city.
Therefore its name is called Babel, because there the LORD confused the language of all the earth; and from there the LORD scattered them abroad over the face of all the earth.
