Numbers 31:16-18

Amplified Bible

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. ¹⁸ But all the young girls who have not known a man intimately, keep alive for yourselves [to marry].
