'Language' in the Bible

The coastland peoples spread out into their lands. These are Japheth’s sons by their clans, in their nations. Each group had its own language.

At one time the whole earth had the same language and vocabulary.

The Lord said, “If they have begun to do this as one people all having the same language, then nothing they plan to do will be impossible for them.

Come, let Us go down there and confuse their language so that they will not understand one another’s speech.”

Therefore its name is called Babylon, for there the Lord confused the language of the whole earth, and from there the Lord scattered them over the face of the whole earth.
