Exodus 33:15-19

And he said unto him, If thy presence go not with me, carry us not up hence. For wherein now shall it be known that I have found favor in thy sight, I and thy people? is it not in that thou goest with us, so that we are separated, I and thy people, from all the people that are upon the face of the earth? And Jehovah said unto Moses, I will do this thing also that thou hast spoken; for thou hast found favor in my sight, and I know thee by name. And he said, Show me, I pray thee, thy glory. And he said, I will make all my goodness pass before thee, and will proclaim the name of Jehovah before thee; and I will be gracious to whom I will be gracious, and will show mercy on whom I will show mercy.
