Deuteronomy 21:10-17

¹⁰And if when thou goest out to war against thine enemies, the Lord thy God should deliver them into thine hands, and thou shouldest take their spoil,

¹¹and shouldest see among the spoil a woman beautiful in countenance, and shouldest desire her, and take her to thyself for a wife,

¹²and shouldest bring her within thine house: then shalt thou shave her head, and pare her nails;

¹³and shalt take away her garments of captivity from off her, and she shall abide in thine house, and shall bewail her father and mother the days of a month; and afterwards thou shalt go in to her and dwell with her, and she shall be thy wife.

¹⁴And it shall be if thou do not delight in her, thou shalt send her out free; and she shall not by any means be sold for money, thou shalt not treat her contemptuously, because thou hast humbled her.

¹⁵And if a man have two wives, the one loved and the other hated, and both the loved and the hated should have born him children, and the son of the hated should be first-born;

¹⁶then it shall be that whensoever he shall divide by inheritance his goods to his sons, he shall not be able to give the right of the first-born to the son of the loved one, having overlooked the son of the hated, which is the first-born.

¹⁷But he shall acknowledge the first-born of the hated one to give to him double of all things which shall be found by him, because he is the first of his children, and to him belongs the birthright.
