Exodus 34:28-30

Darby Translation

²⁸ —And he was there with Jehovah forty days and forty nights; he ate no bread, and drank no water.—And he wrote on the tables the words of the covenant, the ten words.

²⁹ And it came to pass, when Moses came down from mount Sinai—and the two tables of testimony were in Moses' hand, when he came down from the mountain—that Moses knew not that the skin of his face shone through his talking with him.

³⁰ And Aaron and all the children of Israel saw Moses, and behold, the skin of his face shone; and they were afraid to come near him.
