Esther 6:8-12

have them bring a royal robe which the king has worn, and the horse on which the king has ridden, and on whose head a royal turban has been placed;

then order them to hand the robe and the horse over to one of the king’s noble officials, and have them dress the man whom the king desires to honor, and lead him on horseback through the city square, and proclaim before him, ‘So it shall be done for the man whom the king desires to honor.’ ” Haman Must Honor Mordecai

Then the king said to Haman, “Quickly, take the robe and the horse just as you have said, and do so for Mordecai the Jew, who is sitting at the king’s gate; do not fail to do anything of all that you have said.”

So Haman took the robe and the horse, and dressed Mordecai, and led him on horseback through the city square, and proclaimed before him, “So it shall be done for the man whom the king desires to honor.”

Then Mordecai returned to the king’s gate, while Haman hurried home, mourning, with his head covered.
