'Language' in the Bible

From these the coastlands of the nations were separated into their lands, every one according to its language, according to their families, by their nations.

The whole earth had a common language and a common vocabulary.

And the Lord said, "If as one people all sharing a common language they have begun to do this, then nothing they plan to do will be beyond them.

Come, let's go down and confuse their language so they won't be able to understand each other."

That is why its name was called Babel -- because there the Lord confused the language of the entire world, and from there the Lord scattered them across the face of the entire earth.
