God had punished the Israelites for their sin with a plague; as a Father he corrected his own children with a rod. But we read not that any of the Midianites died of the plague; God took another course with them, and punished them with the sword of an enemy, not with the rod of a father. 1. Moses, though the meekest man, and far from a spirit of revenge, is ordered to vex the Midianites and smite them, Num 25:17. Note, We must set ourselves against that, whatever it is, which is an occasion of sin to us, though it be a right eye or a right hand that thus offends us, Mat 5:29, Mat 5:30. This is that holy indignation and revenge which godly sorrow worketh, Co2 7:11. 2. The reason given for the meditating of this revenge is because they vex you with their wiles, Num 25:18. Note, Whatever draws us to sin should be a vexation to us, as a thorn in the flesh. The mischief which the Midianites did to Israel by enticing them to whoredom must be remembered and punished with as much severity as that which the Amalekites did in fighting with them when they came out of Egypt, Exo 17:14. God will certainly reckon with those that do the devil's work in tempting men to sin. See further orders given in this matter, Num 31:2.

Vex the Midianites, and smite them. Go to war with them, and smite them with the sword; not the Moabites, but the Midianites, though they were both confederates against Israel; but God had given a charge not to contend in battle with Moab, Deu 2:9, they were spared for the sake of Lot, from whom they sprang; and, as Jarchi says, for the sake of Ruth, who was to come from them; and so in the Talmud (l); though they did not entirely escape the divine resentment, as appears from Deu 23:3 but the Midianites were the first that advised to send for Balaam, and with them he stayed and was entertained, after he had been dismissed by Balak; and it seems as if it was to them he gave the wicked counsel, to draw Israel into fornication, and so into idolatry, and thereby bring the curse of God upon them; which advice they communicated to the Moabites, and both were concerned in putting it into execution; see Num 22:4.

Zimri, . . . a prince . . . among the Simeonites--The slaughter of a man of such high rank is mentioned as a proof of the undaunted zeal of Phinehas, for there might be numerous avengers of his blood.
