Exodus 34:32-35

32And afterward all the children of Israel came near: and he gave them in commandment all that the LORD had spoken with him in mount Sinai. 33And till Moses finished speaking with them, he put a veil on his face. 34But when Moses went in before the LORD to speak with him, he took the veil off, until he came out. And he came out, and spoke to the children of Israel that which he was commanded. 35And the children of Israel saw the face of Moses, that the skin of Moses’ face shone: and Moses put the veil upon his face again, until he went in to speak with him.
