Esther 9:26–31

26 So they called these days Purim, after the name 4Pur. Therefore, because of all the words of athis letter, what they had seen concerning this matter, and what had happened to them, 27 the Jews established and imposed it upon themselves and their descendants and all who would bjoin them, that without fail they should celebrate these two days every year, according to the written instructions and according to the prescribed time, 28 that these days should be remembered and kept throughout every generation, every family, every province, and every city, that these days of Purim should not fail to be observed among the Jews, and that the memory of them should not perish among their descendants.

29 Then Queen Esther, cthe daughter of Abihail, with Mordecai the Jew, wrote with full authority to confirm this dsecond letter about Purim. 30 And Mordecai sent letters to all the Jews, to ethe one hundred and twenty-seven provinces of the kingdom of Ahasuerus, with words of peace and truth, 31 to confirm these days of Purim at their appointed time, as Mordecai the Jew and Queen Esther had prescribed for them, and as they had decreed for themselves and their descendants concerning matters of their ffasting and lamenting.
