Exodus 34:29-35 New Revised Standard Version (NRSV)
The Shining Face of Moses
29 Moses came down from Mount Sinai. As he came down from the mountain with the two tablets of the covenant[a] in his hand, Moses did not know that the skin of his face shone because he had been talking with God. 30 When Aaron and all the Israelites saw Moses, the skin of his face was shining, and they were afraid to come near him. 31 But Moses called to them; and Aaron and all the leaders of the congregation returned to him, and Moses spoke with them. 32 Afterward all the Israelites came near, and he gave them in commandment all that the Lord had spoken with him on Mount Sinai. 33 When Moses had finished speaking with them, he put a veil on his face; 34 but whenever Moses went in before the Lord to speak with him, he would take the veil off, until he came out; and when he came out, and told the Israelites what he had been commanded, 35 the Israelites would see the face of Moses, that the skin of his face was shining; and Moses would put the veil on his face again, until he went in to speak with him.
Exodus 34:15-16 New Revised Standard Version (NRSV)
15 You shall not make a covenant with the inhabitants of the land, for when they prostitute themselves to their gods and sacrifice to their gods, someone among them will invite you, and you will eat of the sacrifice. 16 And you will take wives from among their daughters for your sons, and their daughters who prostitute themselves to their gods will make your sons also prostitute themselves to their gods.
