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, Pr 6:34; but in God it is holy and just displeasure. Those cannot worship God aright, who do not worship him only.
