'Horse' in the Bible
let them bring royal attire which the king himself has worn and a horse on which the king himself has ridden -- one bearing the royal insignia!
Then let this clothing and this horse be given to one of the king's noble officials. Let him then clothe the man whom the king wishes to honor, and let him lead him about through the plaza of the city on the horse, calling before him, 'So shall it be done to the man whom the king wishes to honor!'"
The king then said to Haman, "Go quickly! Take the clothing and the horse, just as you have described, and do as you just indicated to Mordecai the Jew who sits at the king's gate. Don't neglect a single thing of all that you have said."
So Haman took the clothing and the horse, and he clothed Mordecai. He led him about on the horse throughout the plaza of the city, calling before him, "So shall it be done to the man whom the king wishes to honor!"
