It was a memorable day for God’s people. We have a changing of the guard. Their enemy Haman who had plotted their annihilation was dead and Mordecai had replaced him! The king’s signet ring, which had been worn and misused by Haman, was now placed upon Mordecai’s finger and along with it came the authority to rule on behalf of the king.
When Haman wore the ring the result was hatred and death for God’s people.
When Mordecai wears the ring the result is pardon and liberty for God’s people.
