How shall we do for wives for them that remain, seeing we have sworn by the LORD that we will not give them of our daughters to wives? ... And the congregation sent thither twelve thousand men of the valiantest, and commanded them, saying, Go and smite the inhabitants of Jabeshgilead with the edge of the sword, with the women and the children. And this is the thing that ye shall do, Ye shall utterly destroy every male, and every woman that hath lain by man. And 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 unto the camp to Shiloh.
