Deuteronomy 22:30 Meaning

28If 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;

29Then 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.

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