'Skin' in the Bible

Then God said, "Put your hand back into your bosom." He returned it to his bosom and as soon as he brought it out, it was restored like the rest of his skin.

When Moses came down from Mount Sinai, he had the two tablets in his hand, and he did not know that the skin of his face was ablaze with light because he had been speaking with God.

Aaron and all the Israelis saw Moses and immediately noticed that the skin of his face was shining, and they were afraid to come near him.

The Israelis would see the face of Moses and that the skin of his face shone; then Moses would put the veil back over his face until he went in to speak with God.
