Exodus 34:30-35

And when Aaron and all the children of Israel saw Moses, behold, the skin of his face shone; and they were afraid to come nigh him. And Moses called unto them; and Aaron and all the rulers of the congregation returned unto him: and Moses talked with them. And afterward all the children of Israel came nigh: and he gave them in commandment all that the LORD had spoken with him in mount Sinai. And till Moses had done speaking with them, he put a vail on his face. But when Moses went in before the LORD to speak with him, he took the vail off, until he came out. And he came out, and spake unto the children of Israel that which he was commanded. And the children of Israel saw the face of Moses, that the skin of Moses' face shone: and Moses put the vail upon his face again, until he went in to speak with him.
