Exo Exodus, chapter Book of Exodus, chapter 34
And it came to pass, when Moshe [He Who Draws Out Of The Waters] came down from mount Sinai with the two tables of testimony in Moshe [He Who Draws Out Of The Waters]’ hand, when he came down from the mount, that Moshe [He Who Draws Out Of The Waters] did not know not that the skin of his face shone while he talked with him.
