Exodus 34:29-30
Exodus 34:29-30 NASB1995
It came about when Moses was coming down from Mount Sinai (and the two tablets of the testimony were in Moses’ hand as he was coming down from the mountain), that Moses did not know that the skin of his face shone because of his speaking with Him. So when Aaron and all the sons of Israel saw Moses, behold, the skin of his face shone, and they were afraid to come near him.
