Deuteronomy 22:29

²⁷  For he found her in the field, and the betrothed damsel cried, and there was none to save her.

²⁸  If a man find a damsel that is a virgin, which is not betrothed, and lay hold on her, and lie with her, and they be found;

²⁹  Then the man that lay with her shall give unto the damsel's father fifty shekels of silver, and she shall be his wife; because he hath humbled her, he may not put her away all his days.

³⁰  A man shall not take his father's wife, nor discover his father's skirt.
