Deuteronomy 21:8-18

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.
15 When a man has two wives, one beloved and the other hated, and they have born him sons, both the beloved and the hated; and if the firstborn son is of the one that was hated,
16 then it shall be, when he makes his sons to inherit that which he has, that he may not give the right of the firstborn unto the son of the beloved in preference over the son of the hated, who is indeed the firstborn;
17 but he shall acknowledge the son of the hated as the firstborn by giving him a double portion of all that he has; for he is the beginning of his strength; the right of the firstborn is his.
18 When anyone has a stubborn and rebellious son, who will not obey the voice of his father or the voice of his mother and when they have chastened him, will not hearken unto them,
