1 And the LORD spake unto Moses, saying,
2 Avenge the children of Israel of the Mid'i-anites: afterward shalt thou be gathered unto thy people.
3 And Moses spake unto the people, saying, Arm some of yourselves unto the war, and let them go against the Mid'i-anites, and avenge the LORD of Mid'i-an.
4 Of every tribe a thousand, throughout all the tribes of Israel, shall ye send to the war.
5 So there were delivered out of the thousands of Israel, a thousand of every tribe, twelve thousand armed for war.
6 And Moses sent them to the war, a thousand of every tribe, them and Phin'ehas the son of Ele-a'zar the priest, to the war, with the holy instruments, and the trumpets to blow in his hand.
7 And they warred against the Mid'i-anites, as the LORD commanded Moses; and they slew all the males.
8 And they slew the kings of Mid'i-an, beside the rest of them that were slain; namely, Evi, and Rekem, and Zur, and Hur, and Reba, five kings of Mid'i-an: Ba'laam also the son of Be'or they slew with the sword.
9 And the children of Israel took all the women of Mid'i-an captives, and their little ones, and took the spoil of all their cattle, and all their flocks, and all their goods.
10 And they burnt all their cities wherein they dwelt, and all their goodly castles, with fire.
11 And they took all the spoil, and all the prey, both of men and of beasts.
12 And they brought the captives, and the prey, and the spoil, unto Moses and Ele-a'zar the priest, and unto the congregation of the children of Israel, unto the camp at the plains of Moab, which are by Jordan near Jericho.
13 ¶ And Moses, and Ele-a'zar the priest, and all the princes of the congregation, went forth to meet them without the camp.
14 And Moses was wroth with the officers of the host, with the captains over thousands, and captains over hundreds, which came from the battle.
15 And Moses said unto them, Have ye saved all the women alive?
16 Behold, these caused the children of Israel, through the counsel of Ba'laam, to commit trespass against the LORD in the matter of Pe'or, Num. 25.1-9 and there was a plague among the congregation of the LORD.
17 Now therefore kill every male among the little ones, and kill every woman that hath known man by lying with him.
18 But all the women children, that have not known a man by lying with him, keep alive for yourselves.
19 And do ye abide without the camp seven days: whosoever hath killed any person, and whosoever hath touched any slain, purify both yourselves and your captives on the third day, and on the seventh day.
I wonder how they "purified" the virginal women children that Moses told them to keep for themselves?
