Haman's humiliation was not yet complete. Mordecai, exhausted by his three days' fast, was too weak to mount his horse unaided. Haman had to serve him as footstool, and Mordecai took the opportunity to give him a kick. Haman reminded him of the Scriptural verse: "Rejoice not when thine enemy falleth, and let not thine heart be glad when he is overthrown." Mordecai, however, refused to apply it to himself, for he was chastising, not a personal enemy, but the enemy of his people, and of such it is said in the Scriptures: "And thou shalt tread upon the high places of thine enemies."
