Deuteronomy 22:28-29

ASV(i) 28 If a man find a damsel that is a virgin, that 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.
