Esther 9:23-25

So the Jewish people agreed to do what Mordecai had written to them, and they agreed to hold the celebration every year. Haman son of Hammedatha, the Agagite, was the enemy of all the Jewish people. He had made an evil plan against the Jewish people to destroy them, and he had thrown the Pur (that is, the lot) to choose a day to ruin and destroy them. But when the king learned of the evil plan, he sent out written orders that the evil plans Haman had made against the Jewish people would be used against him. And those orders said that Haman and his sons should be hanged on the platform.
