Exodus 33:18LXX

16For wherein shall it be known here that I and thy people have found grace in thy sight? not in that thou goest with us? so shall we be separated, I and thy people, from all the people that upon the face of the earth.

17And the LORD said unto Moses, I will do this thing also that thou hast spoken: for thou hast found grace in my sight, and I know thee by name.

18And he said, I beseech thee, shew me thy glory.

19And he said, I will make all my goodness pass before thee, and I will proclaim the name of the LORD before thee; and will be gracious to whom I will be gracious, and will shew mercy on whom I will shew mercy.

20And he said, Thou canst not see my face: for there shall no man see me, and live.
