Judges 21:10-12

10And the congregation sent there twelve thousand men of the most valiant, and commanded them, saying, Go and smite the inhabitants of Jabeshgilead with the edge of the sword, with the women and the children.

11And this is the thing that ye shall do, Ye shall utterly destroy every male, and every woman that hath lain by man.1

12And they found among the inhabitants of Jabeshgilead four hundred young virgins, that had known no man by lying with any male: and they brought them to the camp to Shiloh, which is in the land of Canaan.2
