Judges 21:10-12

So the congregation sent twelve divisions of their top men there with the command, “Kill everyone of Jabesh Gilead, including women and children. These are your instructions: Every man and woman who has had sexual intercourse you must kill. But keep the virgins alive.” And that’s what they did. And they found four hundred virgins among those who lived in Jabesh Gilead; they had never had sexual intercourse with a man. And they brought them to the camp at Shiloh, which is in the land of Canaan.
