11 Observe what I command you today. See, I will drive out before you the Amorites, the Canaanites, the Hittites, the Perizzites, the Hivites, and the Jebusites. 12 Take care not to make a covenant with the inhabitants of the land to which you are going, or it will become a snare among you. 13 You shall tear down their altars, break their pillars, and cut down their sacred poles 14 (for you shall worship no other god, because the Lord, whose name is Jealous, is a jealous God). 15 You shall not make a covenant with the inhabitants of the land, for when they prostitute themselves to their gods and sacrifice to their gods, someone among them will invite you, and you will eat of the sacrifice. 16 And you will take wives from among their daughters for your sons, and their daughters who prostitute themselves to their gods will make your sons also prostitute themselves to their gods.
Matthew Henry's Commentary on Exodus 34:11-16
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.
