15 otherwise you might make a covenant with the inhabitants of the land and they would play the harlot with their gods and sacrifice to their gods , and someone might invite you to eat of his sacrifice , 16 and you might take some of his daughters for your sons , and his daughters might play the harlot with their gods and cause your sons also to play the harlot with their gods .

Matthew Henry's Commentary on Exodus 34:15-16

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.
