Genesis 11:4-9

4And they said, Come, 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. 5And Jehovah came down to see the city and the tower, which the children of men builded. 6And Jehovah said, Behold, they are one people, and they have all one language; and this is what they begin to do: and now nothing will be withholden from them, which they purpose to do. 7Come, let us go down, and there confound their language, that they may not understand one another’s speech. 8So Jehovah scattered them abroad from thence upon the face of all the earth: and they left off building the city. 9Therefore was the name of it called Babel; because Jehovah did there confound the language of all the earth: and from thence did Jehovah scatter them abroad upon the face of all the earth.
