Exodus 33:18-20

Thomson(i) 18 Upon which Moses said, Manifest thyself to me. 19 And he said, I will go before thee with my glory and I will call by my name The Lord, before thee; and I will have mercy on whom I please to have mercy; and I will have compassion on whomsoever I compassionate; 20 but, said he, thou canst not see my face; for no man can see my face and live.
