Exodus 34:31

29When Moses came down from Mount Sinai with the two tablets of the covenant in Moses’ hand, when he came down from the mountain, Moses didn’t know that the skin of his face shone by reason of his speaking with him.

30When Aaron and all the children of Israel saw Moses, behold, the skin of his face shone; and they were afraid to come near him.

31Moses called to them, and Aaron and all the rulers of the congregation returned to him; and Moses spoke to them.

32Afterward all the children of Israel came near, and he gave them all the commandments that the LORD had spoken with him on Mount Sinai.

33When Moses was done speaking with them, he put a veil on his face.
