Deuteronomy 21:11-13

Leeser(i) 11 And thou seest among the captives a woman of handsome form, and hast a desire unto her, that thou wouldst take her to thee for wife: 12 Then shalt thou bring her home to thy house; and she shall shave her head, and let grow her nails; 13 And she shall put off the raiment of her captivity from her, and she shall remain in thy house, and weep for her father and her mother a full month; and after that thou mayest go in unto her, and be her husband, that she may become thy wife.
