11 "Observe what I command you this day. Behold, I will drive out before you the Amorites, the Canaanites, the Hittites, the Per'izzites, the Hivites, and the Jeb'usites. 12 Take heed to yourself, lest you make a covenant with the inhabitants of the land whither you go, lest it become a snare in the midst of you. 13 You shall tear down their altars, and break their pillars, and cut down their Ashe'rim 14 (for you shall worship no other god, for the Lord, whose name is Jealous, is a jealous God), 15 lest you make a covenant with the inhabitants of the land, and when they play the harlot after their gods and sacrifice to their gods and one invites you, you eat of his sacrifice, 16 and you take of their daughters for your sons, and their daughters play the harlot after their gods and make your sons play the harlot after 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.
