Exodus 34:29-30
Exodus 34:29-30 NKJV
Now it was so, when Moses came down from Mount Sinai (and the two tablets of the Testimony were in Moses’ hand when he came down from the mountain), that Moses did not know that the skin of his face shone while he talked with Him. So when Aaron and all the children of Israel saw Moses, behold, the skin of his face shone, and they were afraid to come near him.
