'Ring' in the Bible

The king removed his signet ring from his hand and gave it to Hammedatha the Agagite's son Haman, the enemy of the Jewish people.

The king's scribes were summoned on the thirteenth day of the first month, and all that Haman commanded was written to the regional authorities of the king, to the governors who were over each province, and to the officials of each people. This order was translated in the name of King Ahasuerus into the language of each province and bore the seal of the king's signet ring.

The king took off his signet ring that he had taken from Haman and gave it to Mordecai. Esther then put Mordecai in charge of Haman's property.

Now, in the name of the king, you write what seems good to you concerning the Jewish people, and seal it with the king's signet ring, for a document written in the king's name and sealed with the king's signet ring cannot be revoked."

He wrote in the name of King Ahasuerus and sealed it with the king's signet ring. He sent the letters by couriers on horseback, riding steeds especially bred for the king.
