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

Matthew Henry's Commentary on Deuteronomy 12:2

Commentary on Deuteronomy 12:1-4

(Read Deuteronomy 12:1-4)

Moses comes to the statutes he had to give in charge to Israel; and begins with such as relate to the worship of God. The Israelites are charged not to bring the rites and usages of idolaters into the worship of God; not under colour of making it better. We cannot serve God and mammon; nor worship the true God and idols; nor depend upon Christ Jesus and upon superstitious or self-righteous confidences.
