Numbers 31:15 WEB

¹³  Moses, and Eleazar the priest, and all the princes of the congregation, went forth to meet them outside of the camp.

¹⁴  Moses was angry with the officers of the host, the captains of thousands and the captains of hundreds, who came from the service of the war.

¹⁵  Moses said to them, Have you saved all the women alive?

¹⁶  Behold, these caused the children of Israel, through the counsel of Balaam, to commit trespass against Yahweh in the matter of Peor, and so the plague was among the congregation of Yahweh.

¹⁷  Now therefore kill every male among the little ones, and kill every woman who has known man by lying with him.
