Deuteronomy 12:2-4

2You shall utterly destroy all the places where the nations whom you are going to dispossess serve their gods, on the 1high mountains, on the hills, and under every leafy tree.

3And 2you shall tear down their altars and smash their memorial stones to pieces, and burn their 3Asherim in the fire, and cut to pieces the carved images of their gods; and you shall 4eliminate their name from that place.

4You shall not act this way toward the Lord your God.
