Numbers 31:15-17

Amplified Bible

¹⁵ And Moses said to them, “Have you let all the women live? ¹⁶ Look, these [are the women who] caused the Israelites, by the counsel of Balaam, to trespass against the Lord in the matter of Peor, and so a plague came among the congregation of the Lord.^{(A) 17} Now therefore, kill every male among the children, and kill every woman who is not a virgin.
