"Go at once," the king commanded Haman. "Get the robe and the horse and do just as you have suggested for Mordecai the Jew, who sits at the king's gate. Do not neglect anything you have recommended."
So Haman got1 the robe and the horse. He robed Mordecai, and led him on horseback through the city streets, proclaiming before him, "This is what is done for the man the king delights to honor!"
