Exodus 34:30-35

When Aaron and all the people of Israel saw that Moses’ face was shining, they were afraid to go near him. But Moses called to them, so Aaron and all the leaders of the people returned to Moses, and he talked with them. After that, all the people of Israel came near him, and he gave them all the commands that the LORD had given him on Mount Sinai. When Moses finished speaking to the people, he put a covering over his face. Anytime Moses went before the LORD to speak with him, Moses took off the covering until he came out. Then Moses would come out and tell the Israelites what the LORD had commanded. They would see that Moses’ face was shining. So he would cover his face again until the next time he went in to speak with the LORD.
