Esther 9:25

22 as 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.

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

24 because 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;

25 but 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.

26 Therefore 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,

27 the Jews established and imposed on themselves, on their descendants, and on all those who joined themselves to them, so that it should not fail that they would keep these two days according to what was written and according to its appointed time every year;

28 and that these days should be remembered and kept throughout every generation, every family, every province, and every city; and that these days of Purim should not fail from among the Jews, nor their memory perish from their offspring.
