Deuteronomy 12:2
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:
Ye shall utterly destroy all the places wherein the nations which ye shall possess served their gods,.... The temples erected for the worship of them by the Canaanites, of which there were many, as appears by the various names of places given them from the temples in them, as Bethshemesh, Bethbaalmeon, Bethpeor, and others:
upon the high mountains and upon the hills: which they chose to worship on, being nearer the heavens, and which they thought most acceptable to their gods; and some of them had their names from hence, as Baalpeor, in like manner as Jupiter Olympius was called by the Greeks; see Jeremiah 2:20,
and under every green tree; which being shady and solitary, and pleasant to the sight, they fancied their gods delighted in, and this notion prevailed among other nations; and there is scarcely any deity but what had some tree or another devoted to it; as the oak to Jupiter, the laurel to Apollo, the ivy to Bacchus, the olive to Minerva, the myrtle to Venus, &c. see Jeremiah 2:20.
