Exodus 34:12-15

Take heed to yourself, lest you make a covenant with the inhabitants of the land where you are going, lest it be a snare in your midst. But you shall destroy their altars, break their sacred pillars, and cut down their wooden images (for you shall worship no other god, for the LORD, whose name is Jealous, is a jealous God), lest you make a covenant with the inhabitants of the land, and they play the harlot with their gods and make sacrifice to their gods, and one of them invites you and you eat of his sacrifice
