Esther 9:23-25

Thus the Jews undertook what they had started to do, and what Mordecai had written to them. For Haman the son of Hammedatha, the Agagite, the adversary of all the Jews, had schemed against the Jews to destroy them and had cast Pur, that is the lot, to disturb them and destroy them. But when it came to the king’s attention, he commanded by letter that his wicked scheme which he had devised against the Jews, should return on his own head and that he and his sons should be hanged on the gallows.
