Exodus 34:34-35
Exodus 34:34-35 NLT
But 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, and 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.
