Deuteronomy 12:2-3

12:2 You 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. 12:3 You 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.

Deuteronomy 12:30-31

12:30 After they have been destroyed from your presence, be careful not to be ensnared like they are; do not pursue their gods and say, “How do these nations serve their gods? I will do the same.” 12:31 You must not worship the Lord your God the way they do! For everything that is abhorrent to him, everything he hates, they have done when worshiping their gods. They even burn up their sons and daughters before their gods!
