Deuteronomy 12:2-4

2You must by all means destroy all the places where the nations you are about to dispossess worship their gods – on the high mountains and hills and under every leafy tree.

3You must tear down their altars, shatter their sacred pillars, burn up their sacred Asherah poles, and cut down the images of their gods; you must eliminate their very memory from that place.

4You must not worship the Lord your God the way they worship.
