and put aside the clothing of her captivity. After she has lived in your house a full month and mourned her father and mother, you may have relations with her and be her husband, and she shall be your wife. / And if you are not pleased with her, you are to let her go wherever she wishes. But you must not sell her for money or treat her as a slave, since you have dishonored her.
