Deuteronomy 21:10-13

10When thou goest forth to war against thine enemies, and Jehovah thy 1God delivereth them into thy hands, and thou hast taken captives of them,

11and thou seest among the captives a woman of beautiful form, and hast a desire unto her, and takest her as thy wife;

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

13and she shall put the clothes of her captivity from off her, and shall abide in thy house, and bewail her father and mother a full month, and afterwards thou mayest go in unto her, and be her husband, and she shall be thy wife.
