'Shekels of Silver' in the Bible

They will take from him a hundred shekels of silver, which are to be given to the father of the girl, because he has given an evil name to a virgin of Israel: she will go on being his wife, he may never put her away all his life.

Then the man will have to give the virgin's father fifty shekels of silver and make her his wife, because he has put shame on her; he may never put her away all his life.
