Esther 7:9,10

(9) And Harbonah, one of the chamberlains, said before the king, Behold also, the gallows fifty cubits high, which Haman had made for Mordecai, who had spoken good for the king, standeth in the house of Haman. Then the king said, Hang him thereon. (10) So they hanged Haman on the gallows that he had prepared for Mordecai. Then was the king's wrath pacified.

It is not the smallest evidence of the general worthlessness of Haman's character, that this Harbonah was so ready to suggest to the king the gallows Haman had erected to hang Mordecai upon. Thus he fell into his own snare. And the very method he had taken for the destruction of a man who had never injured him, proved his own death. Pause, and contemplate the sure end of the ungodly. And what a display is made of the Lord's providential superintendence through all. So let all thine enemies perish, O Lord. But let them that love thee be as the sun when he goeth forth in his might.
