Exodus 34:29-31

Then Moses came down from Mount Sinai, carrying the two stone tablets of the Agreement in his hands. But he did not know that his face was shining because he had talked with the LORD. 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.
