4. Mose 25:5

The judges were to put to death every one his men, i.e., such of the evil-doers as belonged to his forum, according to the judicial arrangements instituted in Ex 18. This command of Moses to the judges was not carried out, however, because the matter took a different turn.

Israel, having escaped the curse of Balaam, here sustains a great deal of damage and reproach by the counsel of Balaam, who, it seems, before he left Balak, put him into a more effectual way than that which Balak thought of to separate between the Israelites and their God. "The Lord will not be prevailed with by Balaam's charms to ruin them; try if they will not be prevailed with by the charms of the daughters of Moab to ruin themselves." None are more fatally bewitched than those that are bewitched by their own lusts. Here is, I. The sin of Israel; they were enticed by the daughters of Moab both to whoredom and to idolatry (Num 25:1-3). II. The punishment of this sin by the hand of the magistrate (Num 25:4, Num 25:5) and by the immediate hand of God (Num 25:9). III. The pious zeal of Phinehas in slaying Zimri and Cozbi, two impudent sinners (Num 25:6, Num 25:8, Num 25:14, Num 25:15). IV. God's commendation of the zeal of Phinehas (Num 25:10-13). V. Enmity put between the Israelites and the Midianites, their tempters, as at first between the woman and the serpent (Num 25:16, etc.).
