Judges 21:10-11

21:10 So the assembly sent 12,000 capable warriors against Jabesh Gilead. They commanded them, “Go and kill with your swords the inhabitants of Jabesh Gilead, including the women and little children. 21:11 Do this: exterminate every male, as well as every woman who has had sexual relations with a male. But spare the lives of any virgins.” So they did as instructed.
