Deuteronomy 21:4-14

4 and the elders of that city shall bring down the heifer unto a rough valley, which has neither been plowed nor sown, and shall strike off the heifer’s neck there in the valley.
5 And the priests the sons of Levi shall come near; for the LORD thy God has chosen them to minister unto him and to bless in the name of the LORD; and by their word shall every controversy and every stroke be determined.
6 And all the elders of that closest city next to the dead man shall wash their hands over the heifer that is beheaded in the valley.
7 And they shall answer and say, Our hands have not shed this blood, neither have our eyes seen it.
8 Reconcile thy people Israel, whom thou hast ransomed, O LORD, and impute not the innocent blood shed in the midst of thy people Israel. And the blood shall be forgiven them.
9 So shalt thou put away the guilt of innocent blood from among you, when thou shalt do that which is right in the sight of the LORD.
10 When thou goest forth to war against thine enemies, and the LORD thy God has delivered them into thine hands, and thou hast taken them captive,
11 and seest among the captives a beautiful woman and hast a desire unto her that thou would have her to thy wife,
12 then thou shalt bring her home to thine house, and she shall shave her head and pare her nails,
13 and she shall put off the clothing of her captivity and shall remain in thine house and bewail her father and her mother a full month, and after that thou shalt go in unto her and be her husband, and she shall be thy wife.
14 And it shall be, if thou have no delight in her, then thou shalt let her go free, but thou shalt not sell her at all for money; thou shalt not make merchandise of her because thou hast humbled her.
