Esther 9:24-32

24For Haman son of Hammedatha, the Agagite, the enemy of all the Jews, had plotted against the Jews to destroy them and had cast the pur (that is, the lot) for their ruin and destruction. 25But when the plot came to the king’s attention, Or when Esther came before the king he issued written orders that the evil scheme Haman had devised against the Jews should come back onto his own head, and that he and his sons should be impaled on poles. 26(Therefore these days were called Purim, from the word pur .) Because of everything written in this letter and because of what they had seen and what had happened to them, 27the Jews took it on themselves to establish the custom that they and their descendants and all who join them should without fail observe these two days every year, in the way prescribed and at the time appointed.

28These days should be remembered and observed in every generation by every family, and in every province and in every city. And these days of Purim should never fail to be celebrated by the Jews—nor should the memory of these days die out among their descendants. 29So Queen Esther, daughter of Abihail, along with Mordecai the Jew, wrote with full authority to confirm this second letter concerning Purim. 30And Mordecai sent letters to all the Jews in the 127 provinces of Xerxes’ kingdom—words of goodwill and assurance— 31to establish these days of Purim at their designated times, as Mordecai the Jew and Queen Esther had decreed for them, and as they had established for themselves and their descendants in regard to their times of fasting and lamentation. 32Esther’s decree confirmed these regulations about Purim, and it was written down in the records.
