12 Take heed to thyself, that thou make no covenant with the inhabitants of the land to which thou shalt come, lest it be a snare in the midst of thee; 13 but ye shall demolish their altars, shatter their statues, and hew down their Asherahs. 14 For thou shalt worship no other God; for Jehovah—Jealous is his name—is a jealous God; 15 lest thou make a covenant with the inhabitants of the land, and then, when they go a whoring after their gods, and sacrifice unto their gods, thou be invited, and eat of their sacrifice, 16 and thou take of their daughters unto thy sons, and their daughters go a whoring after their gods, and make thy sons go a whoring after their gods.
Matthew Henry's Commentary on Exodus 34:12-16
Commentary on Exodus 34:10-17
(Read Exodus 34:10-17)
The Israelites are commanded to destroy every monument of idolatry, however curious or costly; to refuse all alliance, friendship, or marriage with idolaters, and all idolatrous feasts; and they were reminded not with idolaters, and all idolatrous feats; and they were reminded not to repeat the crime of making molten images. Jealously is called the rage of a man, Proverbs 6:34; but in God it is holy and just displeasure. Those cannot worship God aright, who do not worship him only.
