2 Ruthlessly demolish all the sacred shrines where the nations that you're driving out worship their gods - wherever you find them, on hills and mountains or in groves of green trees. 3 Tear apart their altars. Smash their phallic pillars. Burn their sex-and-religion Asherah shrines. Break up their carved gods. Obliterate the names of those god sites.
Matthew Henry's Commentary on Deuteronomy 12:2-3
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.
