Exodus 34:14

12Be careful, lest you make a covenant with the inhabitants of the land where you are going, lest it be for a snare among you;

13but you shall break down their altars, and dash in pieces their pillars, and you shall cut down their Asherah poles;

14for you shall worship no other god; for the LORD, whose name is Jealous, is a jealous God.

15“Don’t make a covenant with the inhabitants of the land, lest they play the prostitute after their gods, and sacrifice to their gods, and one call you and you eat of his sacrifice;

16and you take of their daughters to your sons, and their daughters play the prostitute after their gods, and make your sons play the prostitute after their gods.
