Exodus 34:13-16

13Rather, you must tear down their altars, smash their sacred stones, and chop down their Asherah poles. 14For you must not worship any other god, for the LORD, whose name is Jealous, is a jealous God.

15Do not make a covenant with the inhabitants of the land, for when they prostitute themselves to their gods and sacrifice to them, they will invite you, and you will eat their sacrifices. 16And when you take some of their daughters as brides for your sons, their daughters will prostitute themselves to their gods and cause your sons to do the same.
