Exodus 34:32-35

32Then all the people of Israel approached him, and Moses gave them all the instructions the Lord had given him on Mount Sinai.

33When Moses finished speaking with them, he covered his face with a veil.

34But whenever he went into the Tent of Meeting to speak with the Lord, he would remove the veil until he came out again. Then he would give the people whatever instructions the Lord had given him,

35and the people of Israel would see the radiant glow of his face. So he would put the veil over his face until he returned to speak with the Lord.
