Numbers 31:16-18

New Revised Standard Version, Anglicised Catholic Edition

¹⁶ These women here, on Balaam’s advice, made the Israelites act treacherously against the Lord in the affair of Peor, so that the plague came among the congregation of the Lord. ¹⁷ Now therefore, kill every male among the little ones, and kill every woman who has known a man by sleeping with him. ¹⁸ But all the young girls who have not known a man by sleeping with him, keep alive for yourselves.
