Exodus 34:14-16 Living Bible (TLB)
14 For you must worship no other gods, but only Jehovah, for he is a God who claims absolute loyalty and exclusive devotion.
15 “No, do not make a peace treaty of any kind with the people living in the land, for they are spiritual prostitutes, committing adultery against me by sacrificing to their gods.[a] If you become friendly with them and one of them invites you to go with him and worship his idol, you are apt to do it. 16 And you would accept their daughters, who worship other gods, as wives for your sons—and then your sons would commit adultery against me by worshiping their wives’ gods.
