Esther 8:1-3

On that day King Ahasuerus gave the house of Haman, the enemy of the Jews, to Queen Esther; and Mordecai came before the king, for Esther had disclosed what he was to her. The king took off his signet ring which he had taken away from Haman, and gave it to Mordecai. And Esther set Mordecai over the house of Haman. Then Esther spoke again to the king, fell at his feet, wept and implored him to avert the evil scheme of Haman the Agagite and his plot which he had devised against the Jews.
