Judges 21:10-12

10And the congregation sent twelve thousand of the most courageous men there, and commanded them saying, “Go and strike the inhabitants of Jabesh-gilead with the sword, including the women and the children.

11And this is the thing that you shall do; you shall utterly destroy every male and every woman who is not a virgin.”

12And they found among the inhabitants of Jabesh-gilead four hundred young virgins who had not known a man intimately; and they brought them to the camp at Shiloh, which is in the land of Canaan.
