'Skin' in the Bible

Then He said, “Put your hand back inside your cloak.” He put his hand back inside his cloak, and when he took it out, it had again become like the rest of his skin.

As Moses descended from Mount Sinai—with the two tablets of the testimony in his hands as he descended the mountain—he did not realize that the skin of his face shone as a result of his speaking with the Lord.

When Aaron and all the Israelites saw Moses, the skin of his face shone! They were afraid to come near him.
