C. F. Keil and Franz Delitzsch on Deuteronomy 22:18-19

Deu 22:18-19

The elders, as the magistrates of the place, were then to send for the man who had so calumniated his young wife, and to chastise him (יסּר, as in Deu 21:18, used to denote bodily chastisement, thought the limitation of the number of strokes to forty save one, may have been a later institution of the schools); and in addition to this they were to impose a fine upon him of 100 shekels of silver, which he was to pay to the father of the young wife for his malicious calumniation of an Israelitish maiden, - twice as much as the seducer of a virgin was to pay to her father for the reproach brought upon him by the humiliation of his daughter (Deu 22:29); and lastly, they were to deprive the man of the right of divorce from his wife.
