And the king took off his ring, which he had taken from Haman, and gave it unto Mordecai. And Esther set Mordecai over the house of Haman.
The king took off his ring ... and gave it unto Mordecai - by that act transferring to him all the power and authority (cf. Gen. 12:42) which the ring symbolized, and promoting him to the high dignity which Haman had formerly filled.
Esther set Mordecai over the house of Haman - as her steward, or factor, to manage that large and opulent estate which had been assigned to her.
