Esther 6:9, 11

Then let this robe and horse be delivered to the hand of one of the king’s most noble princes, that he may array the man whom the king delights to honor. Then parade him on horseback through the city square, and proclaim before him: ‘Thus shall it be done to the man whom the king delights to honor!’ ”

So Haman took the robe and the horse, arrayed Mordecai and led him on horseback through the city square, and proclaimed before him, “Thus shall it be done to the man whom the king delights to honor!”
