You shall not make a post idol of any trees near unto the altar of the LORD your God, which you shall make you. Neither shall you set up any image; which the LORD your God hates. Deuteronomy 16:21-22 KJV 2000
Matthew Henry’s Commentary:
Care is taken to prevent following the idolatrous customs of the heathen. Nothing belies God more, or tends more to corrupt the minds of men, than representing and worshipping, by an image, that God, who is an almighty and eternal Spirit, present every where. Alas! even in gospel days, and under a better dispensation, established upon better promises, there is a tendency to set up idols, under one form or another, in the human heart.
