When Haman entered, the king asked him, "What should be done for the man the king delights to honor?" Now Haman thought to himself, "Who is there that the king would rather honor than me?"
So he answered the king, "For the man the king delights to honor,
have them bring a royal robe1 the king has worn and a horse2 the king has ridden, one with a royal crest placed on its head.

Then let the robe and horse be entrusted to one of the king's most noble princes. Let them robe the man the king delights to honor, and lead him on the horse through the city streets, proclaiming before him, 'This is what is done for the man the king delights to honor!3' "
