Exodus 34:29-33

29And 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.

30And 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.

31And Moses called to them; and they turned to him, — Aaron and all the principal men of the assembly; and Moses talked with them.

32And afterwards, all the children of Israel came near; and he gave them in commandment all that Jehovah had spoken with him on mount Sinai.

33And Moses ended speaking with them; and he had put on his face a veil.
