Esther revealed herself to her husband as a Jewess, exposed Haman’s plot, and the king sent Haman to a gallows Haman had erected to kill Jews. Esther is honored among Jews for saving the race, and she is honored by Christians as well.
BTTT!
Haman may have intended to hang other Jews on that gallows as well but he built it to hang Esther's cousin Mordecai.
