'Shekels of Silver' in the Bible

And they shall fine him a hundred shekels of silver, and give them unto the father of the young woman, because he has brought an evil name upon a virgin of Israel: and she shall be his wife; he may not put her away all his days.

Then the man that lay with her shall give unto the young woman's father fifty shekels of silver, and she shall be his wife; because he has violated her, he may not put her away all his days.
