Judges 21:10-12

10So all the Israelites decided to send an army of 12,000 soldiers to attack Jabesh Gilead. They commanded them, ‘Use your swords to kill everyone there, including the women and children.

11This is what you must do: Kill every male and every woman who has slept with a man. But do not kill the women who have never had sex.’

12The Israelite army attacked Jabesh Gilead. They found 400 young women who had not had sex with anyone. They took the women back to their camp at Shiloh in Canaan.
