'Papers' in the Bible

If the second husband rejects her and then divorces her, gives her the papers, and evicts her from his house, or if the second husband who married her dies,

She also saw that I gave wayward Israel her divorce papers and sent her away because of her adulterous worship of other gods. Even after her unfaithful sister Judah had seen this, she still was not afraid, and she too went and gave herself like a prostitute to other gods.
