14And Moses was wroth with the officers of the host, with the captains over thousands, and captains over hundreds, which came from the battle. 15And Moses said unto them, Have ye saved all the women alive? 16Behold, 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. 17Now therefore kill every male among the little ones, and kill every woman that hath known man by lying with him. 18But all the women children, that have not known a man by lying with him, keep alive for yourselves.
