Esther 7:7-10

Then in his fury, the king stood up from drinking wine and went into the palace garden [to decide what he should do]; but Haman stayed to plead for his life from Queen Esther, for he saw that harm had been determined against him by the king. When the king returned from the palace garden to the place where they were drinking wine, Haman was falling on the couch where Esther was. Then the king said, “Will he even attempt to assault the queen with me in the palace?” As the king spoke those words, the servants covered Haman’s face [in preparation for execution]. Then Harbonah, one of the eunuchs serving the king said, “Now look, there are gallows fifty cubits (75 ft.) high standing at Haman’s house, which Haman made for Mordecai, whose good warning saved the king.” And the king said, “Hang him on it.” So they hanged Haman on the gallows that he had prepared for Mordecai. Then the king’s anger subsided.
