Deuteronomy 12:2-3

2You will chase out the nations who live there. Then you must destroy completely all the places where those people worship their gods. Those places are on the tops of mountains and hills, and under big green trees.

3You must break into pieces their altars and stone pillars. Burn their Asherah poles. Knock down the images of their gods. Destroy those places so that nobody remembers the false gods.
