Numbers 31:13 MSG

[13] Moses, Eleazar, and all the leaders of the congregation went to meet the returning army outside the camp. Moses was furious with the army officers—the commanders of thousands and commanders of hundreds—as they came back from the battlefield: “What’s this! You’ve let these women live! They’re the ones who, under Balaam’s direction, seduced the People of Israel away from God in that mess at Peor, causing the plague that hit God’s people. Finish your job: kill all the boys. Kill every woman who has slept with a man. The younger women who are virgins you can keep alive for yourselves.
