Exodus 34:32-35

32And 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. 33And when Moses had done 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 spake unto 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.
