Exodus 34:29-31

And it came to pass, when Moses came down from mount Si´nai with the two tables of testimony in Moses' hand, when he came down from the mount, that Moses wist not that the skin of his face shone while he talked with him. And when Aaron and all the children of Israel saw Moses, behold, the skin of his face shone; and they were afraid to come nigh him. And Moses called unto them; and Aaron and all the rulers of the congregation returned unto him: and Moses talked with them.
