Deuteronomy 22:19

19and they shall fine him a hundred shekels
A  shekel was about 2/5 ounce or 11 grams
of silver and give them to the father of the young woman, because he has brought a bad name upon a virgin
Or girl of marriageable age
of Israel. And she shall be his wife. cHe may not divorce her all his days.

1 Thus says the Lord:
Where is dyour mother’s certificate of divorce,
with which eI sent her away?
Or fwhich of my creditors is it
to whom I have sold you?
gBehold, for your iniquities you were sold,
and for your transgressions your mother was sent away.

Mark 10:2
