Exodus 34:29-33

When 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. When Aaron and all the Israelites saw Moses, his face was radiant, and they were afraid to come near him. But Moses called to them; so Aaron and all the leaders of the community came back to him, and he spoke to them. Afterward all the Israelites came near him, and he gave them all the commands the LORD had given him on Mount Sinai. When Moses finished speaking to them, he put a veil over his face.
