'Certificate' in the Bible

“If a man marries a woman, but she becomes displeasing to him because he finds something improper about her, he may write her a divorce certificate, hand it to her, and send her away from his house.

and the second man hates her, writes her a divorce certificate, hands it to her, and sends her away from his house or if he dies,

This is what the Lord says:Where is your mother’s divorce certificatethat I used to send her away?Or who were My creditors that I sold you to?Look, you were sold for your iniquities,and your mother was put awaybecause of your transgressions.

I observed that it was because unfaithful Israel had committed adultery that I had sent her away and had given her a certificate of divorce. Nevertheless, her treacherous sister Judah was not afraid but also went and prostituted herself.
