Esther 8:7-8

King Xerxes said to Queen Esther and Mordecai the Jew: “I’ve given Haman’s estate to Esther and he’s been hanged on the gallows because he attacked the Jews. So go ahead now and write whatever you decide on behalf of the Jews; then seal it with the signet ring.” (An order written in the king’s name and sealed with his signet ring is irrevocable.)
