Genesis 11:1-9
>And the whole earth was of one language, and of one speech.
>2 And it came to pass, as they journeyed from the east, that they found a plain in the land of Shinar; and they dwelt there.
>3 And they said one to another, Go to, let us make brick, and burn them thoroughly. And they had brick for stone, and slime had they for morter.
>4 And they said, Go to, let us build us a city and a tower, whose top may reach unto heaven; and let us make us a name, lest we be scattered abroad upon the face of the whole earth.
>5 And the Lord came down to see the city and the tower, which the children of men builded.
>6 And the Lord said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do.
>7 Go to, let us go down, and there confound their language, that they may not understand one another's speech.
>8 So the Lord scattered them abroad from thence upon the face of all the earth: and they left off to build the city.
>9 Therefore is the name of it called Babel; because the Lord did there confound the language of all the earth: and from thence did the Lord scatter them abroad upon the face of all the earth.
>God literally divided man when he became of one language and culture
