(3) Arm some of yourselves . . . --Better, Arm from among you (or, from those with you) men for the war. The details of the selection are contained in the next verse.
Verse 3. - Avenge the Lord of Midian. God, speaking to Moses, had commanded a war of vengeance; Moses, speaking to the people, is careful to command a war of religious vengeance. In seducing the people of the Lord the Midianites had insulted and injured the majesty of God himself. On the question why Midian only, and not Moab also, was punished see on Numbers 25:17. It is to be remembered that, however hateful the sins of licentiousness and idolatry may be, they have never aroused by themselves the exterminating wrath of God. Midian was smitten because he had deliberately used these sins as weapons wherewith to take the life of Israel.
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.
And Moses spake unto the people, saying,.... In obedience to the divine command; this must be supposed to be spoken to the heads or princes of the tribes:
arm some of yourselves unto the war: not the whole body of the militia, 600,000 men and upwards, only some of them, and these choice and select men; and, according to the Jewish writers, good men, who, detesting the sins of lewdness and idolatry, would more strictly and severely avenge themselves on the Midianites for drawing their brethren into those sins, whereby they fell; and so Jarchi calls them righteous men:
and let them go against the Midianites, and avenge the Lord of Midian: what the Lord calls the vengeance of the Israelites, Moses calls the vengeance of the Lord, because they were the Lord's people, and his cause and theirs the same: and because the sins they were drawn into by the Midianites were not only against themselves, and to their prejudice, but against the Lord and to the dishonour of his name.
