Exodus 34:11-15

“Be sure to comply with what I am commanding you this day: behold, I am going to drive out the Amorite from you, and the Canaanite, the Hittite, the Perizzite, the Hivite, and the Jebusite.

But rather, you are to tear down their altars and smash their memorial stones, and cut down their Asherim

—for you shall not worship any other god, because the Lord, whose name is Jealous, is a jealous God—

otherwise you might make a covenant with the inhabitants of the land, and they would prostitute themselves with their gods and sacrifice to their gods, and someone might invite you to eat of his sacrifice,
