Esther 9:24

22as the days in which the Jews had rest from their enemies, and the month which was turned to them from sorrow to gladness, and from mourning into a holiday; that they should make them days of feasting and gladness, and of sending presents of food to one another, and gifts to the needy.

23The Jews accepted the custom that they had begun, as Mordecai had written to them,

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

25but when this became known to the king, he commanded by letters that his wicked plan, which he had planned against the Jews, should return on his own head, and that he and his sons should be hanged on the gallows.

26Therefore they called these days “Purim”, from the word “Pur.” Therefore because of all the words of this letter, and of that which they had seen concerning this matter, and that which had come to them,
