Israel Warned of the Idolatry of Canaan

11 'Observe for thyself that which I am commanding thee to-day: lo, I am casting out from before thee the Amorite, and the Canaanite, and the Hittite, and the Perizzite, and the Hivite, and the Jebusite; 12 take heed to thyself, lest thou make a covenant with the inhabitant of the land into which thou art going, lest it become a snare in thy midst; 13 for their altars ye break down, and their standing pillars ye shiver, and its shrines ye cut down; 14 for ye do not bow yourselves to another god—for Jehovah, whose name 'is' Zealous, is a zealous God. 15 'Lest thou make a covenant with the inhabitant of the land, and they have gone a-whoring after their gods, and have sacrificed to their gods, and 'one' hath called to thee, and thou hast eaten of his sacrifice, 16 and thou hast taken of their daughters to thy sons, and their daughters have gone a-whoring after their gods, and have caused thy sons to go a-whoring after their gods;

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.
