Genesis 11:7-9

7 Come, let's go down and confuse their language, so that they won't understand each other's speech."
8 So from there ADONAI scattered them all over the earth, and they stopped building the city.
9 For this reason it is called Bavel [confusion] - because there ADONAI confused the language of the whole earth, and from there ADONAI scattered them all over the earth.
