Lets turn to the Old Testament. For the moment, focus your attention on the Book of Numbers.
You are about to learn that Moses ORDERED his followers to commit war crimes. The most heinous were crimes were committed against women and children. Moses ordered:
The slaughter of non-combatant women prisoners.
The slaughter of non-combatant young boy prisoners.
The use of young girl prisoners as Israelite sex slaves.
How Moses treated Gentile women and children.
Background: In Exodus Chapter 2, Moses flees Egypt because he has killed an Egyptian. He passes through the land of the Midianites, who befriend him. Moses lived among them for a while and “took to wife” a Midianite woman, Zipporah. Moses and Zipporah have a son, Gershom.
The Israelites , in the meantime are getting too "friendly" with the Midianites. A significant number of Israelites start cohabiting with Midianite girls and worshipping Midianite gods.
Moses orders the beheading of the Israelites who are encouraging the mix. A divine plague — presumably sent by Jehovah kills 24,000 of the offending Israelites.
Numbers Chapter 25 urges Israelites to “vex” and “smite” or “harass” the Midianites.
Time passes. Jehovah and Moses spend Chapter 26 of Numbers organizing a huge census and Chapters 27, 28, 29 and 30 laying down various laws for the Israelites.
But by Numbers Chapter 31 — for reasons not explained — Jehovah’s attention becomes fastened once more on the Midianites. He orders Moses to kill them. Why? For what happened in Chapter 25.
Thus Jehovah orders an unprovoked attack on Moses’ in-laws. Not a problem. Moses sends off thousands of his troops to slay them.
The Israelites kill the five Midianite kings and all the other Midianite adult males. They loot the cities and burn them, and take the women and children in captivity.
But when they return, Moses is furious. “Have you kept all the women alive? These women caused the children of Israel to trespass against the Lord . . .” (New King James translation, Verses 15, 16).
Moses then orders:
1) all the non-virgin women captives to be killed
2) all the boy children captives to be killed
3) all the virgin girl captives to be saved for the use of the Israelite men.
Check out Numbers, Chapter 31, King James Version
(13) And Moses, and Eleazar 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 Balaam, to commit trespass against the LORD in the matter of Peor, 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.
(13) Moses, Eleazar the priest, and all the leaders of the community went to meet them outside the camp. (14) But Moses was furious with all the generals and captains [a] who had returned from the battle.
(15) “Why have you let all the women live?” he demanded.
(16) “These are the very ones who followed Balaam’s advice and caused the people of Israel to rebel against the Lord at Mount Peor. They are the ones who caused the plague to strike the Lord’s people.
(17) So kill all the boys and all the women who have had intercourse with a man.
( 18 ) Only the young girls who are virgins may live; you may keep them for yourselves.
The rest of Chapter 31 is concerned with distributing the Midianite plunder. Thirty-two thousand (32,000) virgin girls were counted in the booty (Verse 35). Thirty-two of these were given to “the Lord.” That is, 32 of these little girls were set aside for the Levities (heave offerings), to be used as concubines (Verses 40 and 41).
