Deuteronomy 21:9

6 And all the elders of that city, who are nearest unto the slain man, shall wash their hands over the heifer whose neck was broken in the valley;

7 and they shall answer and say, Our hands have not shed this blood, neither have our eyes seen it.

8 Forgive, O Jehovah, thy people Israel, whom thou hast redeemed, and suffer not innocent blood [to remain] in the midst of thy people Israel. And the blood shall be forgiven them.

9 So shalt thou put away the innocent blood from the midst of thee, when thou shalt do that which is right in the eyes of Jehovah.

10 When thou goest forth to battle against thine enemies, and Jehovah thy God delivereth them into thy hands, and thou carriest them away captive,

11 and seest among the captives a beautiful woman, and thou hast a desire unto her, and wouldest take her to thee to wife;

12 then thou shalt bring her home to thy house; and she shall shave her head, and pare her nails;
