Deuteronomy 21:13-14

New International Version

¹³ and put aside the clothes she was wearing when captured. After she has lived in your house and mourned her father and mother for a full month,^(A) then you may go to her and be her husband and she shall be your wife. ¹⁴ If you are not pleased with her, let her go wherever she wishes. You must not sell her or treat her as a slave, since you have dishonored her.^(B)
