Genesis 11:6-9

King James Version

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.
