Israel Takes Vengeance on Midian

311 The Lord said to Moses, 2 "Take vengeance on the Midianites for the Israelites. After that, you will be gathered to your people." 3 So Moses said to the people, "Arm some of your men to go to war against the Midianites so that they may carry out the Lord's vengeance on them. 4 Send into battle a thousand men from each of the tribes of Israel." 5 So twelve thousand men armed for battle, a thousand from each tribe, were supplied from the clans of Israel. 6 Moses sent them into battle, a thousand from each tribe, along with Phinehas son of Eleazar, the priest, who took with him articles from the sanctuary and the trumpets for signaling.

Commentary on Numbers 31:1-6

(Read Numbers 31:1-6)

All who, without commission from God, dare to execute private revenge, and who, from ambition, covetousness, or resentment, wage war and desolate kingdoms, must one day answer for it. But if God, instead of sending an earthquake, a pestilence, or a famine, be pleased to authorize and command any people to avenge his cause, such a commission surely is just and right. The Israelites could show such a commission, though no persons now can do so. Their wars were begun and carried on expressly by Divine direction, and they were enabled to conquer by miracles. Unless it can be proved that the wicked Canaanites did not deserve their doom, objectors only prove their dislike to God, and their love to his enemies. Man makes light of the evil of sin, but God abhors it. This explains the terrible executions of the nations which had filled the measure of their sins.
