'Shekels of Silver' in the Bible

fine him 100 shekels of silver, and then give them to the young lady's father, because he defamed a virgin of Israel. She is to remain his wife and he can't divorce her as long as he lives.

then the man who raped her must give 50 shekels of silver to the girl's father. Furthermore, he must marry her. Because he had violated her, he is to not divorce her as long as he lives.
