2 You shall surely destroy all the places in which the nations that you shall dispossess served their gods, on the high mountains, and on 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.
