Deuteronomy 12:2-3

2Ye shall utterly destroy all the places wherein the nations which ye shall dispossess have served their 1gods, upon the high mountains, and upon the hills, and under every green tree;

3and ye shall break down their altars, and shatter their statues, and burn their Asherahs with fire; and ye shall hew down the graven images of their 2gods, and ye shall destroy the names of them out of that place.
