Esther 8:7-8

7King Xerxes replied to Queen Esther and to Mordecai the Jew, “Because Haman attacked the Jews, I have given his estate to Esther, and they have impaled him on the pole he set up.

8Now write another decree in the king’s name in behalf of the Jews as seems best to you, and seal it with the king’s signet ring—for no document written in the king’s name and sealed with his ring can be revoked.”
