And they warred against the Midianites, as the Lord commanded Moses,.... Whether the Midianites came out against them with an army, and there was a pitched battle between them, is not certain; however the Israelites committed acts of hostility upon them, by entering their cities, plundering their houses, and slaying the inhabitants of them; the Targum of Jonathan is,"they warred against Midian, and surrounded it in the three corners of it, as the Lord commanded Moses;''for, as Maimonides (b) observes from tradition,"when they besiege a city to take it, they do not surround it in the four corners of it, but in the three corners of it, and leave a place to flee out, that everyone that would might escape for his life, as it is said, "and they warred against Midian, as the Lord commanded Moses"; by report, or from tradition, it is learnt that so he commanded him;''that is, in such a manner to besiege a city; but for this there is only tradition, for it is not mentioned among the rules after directed to in such a case, Deuteronomy 20:10,

and they slew all the males; which fell into their hands; for, no doubt, there were multitudes that made their escape, since in later times we read of the Midianites, as a very powerful people, and very distressing to Israel, Judges 6:1 these, as Aben Ezra observes, they slew, were such as were grown up, for as for their little ones, them they spared and carried captive, Numbers 31:9.

Of the campaign itself, the results are all that is recorded. No doubt it terminated with a great battle, in which the Midianites were taken unawares and completely routed. As it was a war of vengeance of Jehovah, the victors slew all the males, i.e., all the adult males, as the sequel shows, without quarter; and "upon those that were slain," i.e., in addition to them, the five Midianitsh kings and Balaam, who first advised the Midianites, according to Numbers 31:16, to tempt the Israelites to idolatry. The five kings were chiefs of the larger or more powerful of the Midianitish tribes, as Zur is expressly said to have been in Numbers 25:15. In Joshua 13:21 they are called "vassals of Sihon," because Sihon had subjugated them and made them tributary when he first conquered the land. The women and children of the Midianites were led away prisoners; and their cattle (behemah, beasts of draft and burden, as in Exodus 20:10), and their flocks, and their goods taken away as spoil. The towns in their dwellings, and all their villages (tiroth, tent-villages, as in Genesis 25:16), were burnt down. The expression "towns in their dwellings" leads to the conclusion that the towns were not the property of the Midianites themselves, who were a nomad people, but that they originally belonged in all probability to the Moabites, and had been taken possession of by the Amorites under Sihon. This is confirmed by Joshua 13:21, according to which these five Midianitish vassals of Sihon dwelt in the land, i.e., in the kingdom of Sihon. This also serves to explain why the conquest on their country is not mentioned in the account before us, although it is stated in Joshua (l.c.), that it was allotted to the Reubenites with the kingdom of Sihon.

And they warred against the Midianites, as the LORD commanded Moses; and they slew all the males.

31:7 All the males - Namely all who lived in those parts, for colonies of them, were sent forth to remoter places, which therefore had no hand either in their former sin, or in this present ruling. And herein they did according to God's own order concerning such people, Deu 20:13, only their fault was, that they did not consider the special reason which they had to involve the women in the destruction.

7. they slew all the males-This was in accordance with a divine order in all such cases (De 20:13). But the destruction appears to have been only partial-limited to those who were in the neighborhood of the Hebrew camp and who had been accomplices in the villainous plot of Baal-peor (Nu 25:1-3), while a large portion of the Midianites were absent on their pastoral wanderings or had saved themselves by flight. (Compare Jud 6:1).

31:7-12 The Israelites slew the Kings of Midian. They slew Balaam. God's overruling providence brought him thither, and their just vengeance found him. Had he himself rightly believed what he had said of the happy state of Israel, he would not have thus herded with the enemies of Israel. The Midianites' wicked wiles were Balaam's projects: it was just that he should perish with them, Ho 4:5. They took the women and children captives. They burnt their cities and castles, and returned to the camp.
