Numbers 31:16-18

New International Version - UK

¹⁶ ‘They were the ones who followed Balaam’s advice and enticed the Israelites to be unfaithful to the Lord in the Peor incident, so that a plague struck the Lord’s people. ¹⁷ Now kill all the boys. And kill every woman who has slept with a man, ¹⁸ but save for yourselves every girl who has never slept with a man.
