Exodus 34:29-35

When Moses came down from Mount Sinai carrying the two Tablets of The Testimony, he didn’t know that the skin of his face glowed because he had been speaking with GOD. Aaron and all the Israelites saw Moses, saw his radiant face, and held back, afraid to get close to him. Moses called out to them. Aaron and the leaders in the community came back and Moses talked with them. Later all the Israelites came up to him and he passed on the commands, everything that GOD had told him on Mount Sinai. When Moses finished speaking with them, he put a veil over his face, but when he went into the presence of GOD to speak with him, he removed the veil until he came out. When he came out and told the Israelites what he had been commanded, they would see Moses’ face, its skin glowing, and then he would again put the veil on his face until he went back in to speak with GOD.
