Esther 9:23

21To stablish this among them, that they should keep the fourteenth day of the month Adar, and the fifteenth day of the same, yearly,

22As the days wherein the Jews rested from their enemies, and the month which was turned unto them from sorrow to joy, and from mourning into a good day: that they should make them days of feasting and joy, and of sending portions one to another, and gifts to the poor.

23And the Jews undertook to do as they had begun, and as Mordecai had written unto them;

24Because Haman the son of Hammedatha, the Agagite, the enemy of all the Jews, had devised against the Jews to destroy them, and had cast Pur, that is, the lot, to consume them, and to destroy them;

25But when Esther came before the king, he commanded by letters that his wicked device, which he devised against the Jews, should return upon his own head, and that he and his sons should be hanged on the gallows.
