“Ye shall utterly destroy all the places, wherein the nations which ye shall possess served their gods, upon the high mountains, and upon the hills, and under every green tree:”
King James Version (KJV)
12:2 All the places - Temples, chapels, altars, groves, as appears from other scriptures. Green - tree - As the Gentiles consecrated divers trees to their false gods, so they worshipped these under them.
