Exodus 33:14-16

And he said, My presence shall go with thee, and I will give thee rest. And he said unto him, If thy presence go not with me, carry us not up hence. For wherein shall it be known here that I and thy people have found grace in thy sight? is it not in that thou goest with us? so shall we be separated, I and thy people, from all the people that are upon the face of the earth.
