So the king removed the signet ring from his finger and gave it to Haman son of Hammedatha, the Agagite, the enemy of the Jews. / On the thirteenth day of the first month, the royal scribes were summoned and the order was written exactly as Haman commanded the royal satraps, the governors of each province, and the officials of each people, in the script of each province and the language of every people. It was written in the name of King Xerxes and sealed with the royal signet ring.
Esther 8:2–10
The king removed the signet ring he had recovered from Haman and presented it to Mordecai. And Esther appointed Mordecai over the estate of Haman. / And once again, Esther addressed the king. She fell at his feet weeping and begged him to revoke the evil scheme of Haman the Agagite, which he had devised against the Jews. / The king extended the gold scepter toward Esther, and she arose and stood before the king.
