11 Observe what I command you this day. Behold, I am driving out from before you the Amorite and the Canaanite and the Hittite and the Perizzite and the Hivite and the Jebusite. 12 Take heed to yourself, lest you make a covenant with the inhabitants of the land where you are going, lest it be a snare in your midst. 13 But you shall destroy their altars, break their sacred pillars, and cut down their wooden images 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 they play the harlot with their gods and make sacrifice to their gods, and one of them invites you and you eat of his sacrifice, 16 and you take of his daughters for your sons, and his daughters play the harlot with their gods and make your sons play the harlot with 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.
