Matthew Henry Commentary Deuteronomy 12:1-4

"These are the statutes and the ordinances which ye shall observe to do in the land which Jehovah, the God of thy fathers, hath given thee to possess it, all the days that ye live upon the earth. Ye shall surely destroy all the places wherein the nations that ye shall dispossess served their gods, upon the high mountains, and upon the hills, and under every green tree: and ye shall break down their altars, and dash in pieces their pillars, and burn their Asherim with fire; and ye shall hew down the graven images of their gods; and ye shall destroy their name out of that place. Ye shall not do so unto Jehovah your God." — Deuteronomy 12:1-4 (ASV)

Moses comes to the statutes he was to entrust 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 the pretext 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 trusts.
