Esther 9:20-28

Purim Established 20Mordecai recorded these events, and he sent letters to all the Jews throughout the provinces of King Xerxes, near and far, 21to have them celebrate annually the fourteenth and fifteenth days of the month of Adar

22as the time when the Jews got relief from their enemies, and as the month when their sorrow was turned into joy and their mourning into a day of celebration. He wrote them to observe the days as days of feasting and joy and giving presents of food to one another and gifts to the poor. 23So the Jews agreed to continue the celebration they had begun, doing what Mordecai had written to them. 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.
