Exodus 34:11-17

11Observe thou that which I command thee this day: behold, I drive out before thee the Amorite, and the Canaanite, and the Hittite, and the Perizzite, and the Hivite, and the Jebusite. 12Take heed to thyself, lest thou make a covenant with the inhabitants of the land whither thou goest, lest it be for a snare in the midst of thee: 13but ye shall break down their altars, and dash in pieces their pillars, and ye shall cut down their Asherim; 14(for thou shalt worship no other god: for Jehovah, whose name is Jealous, is a jealous God); 15lest thou make a covenant with the inhabitants of the land, and they play the harlot after their gods, and sacrifice unto their gods, and one call thee and thou eat of his sacrifice; 16and thou take of their daughters unto thy sons, and their daughters play the harlot after their gods, and make thy sons play the harlot after their gods. 17Thou shalt make thee no molten gods.
