Exodus 34:10-14

Then God said, “Behold, I am going to make a covenant. Before all your people I will perform miracles which have not been produced in all the earth nor among any of the nations; and all the people among whom you live will see the working of the LORD, for it is a fearful thing that I am going to perform with you. “Be sure to observe what I am commanding you this day: behold, I am going to drive out the Amorite before you, and the Canaanite, the Hittite, the Perizzite, the Hivite and the Jebusite. Watch yourself that you make no covenant with the inhabitants of the land into which you are going, or it will become a snare in your midst. But rather, you are to tear down their altars and smash their sacred pillars and cut down their Asherim —for you shall not worship any other god, for the LORD, whose name is Jealous, is a jealous God
