Exodus 34:29-33

29When Moses came down from Mount Sinai with the two tablets of the covenant law in his hands, he was not aware that his face was radiant because he had spoken with the Lord.

30When Aaron and all the Israelites saw Moses, his face was radiant, and they were afraid to come near him.

31But Moses called to them; so Aaron and all the leaders of the community came back to him, and he spoke to them.

32Afterward all the Israelites came near him, and he gave them all the commands the Lord had given him on Mount Sinai.

33When Moses finished speaking to them, he put a veil over his face.
