Esther 9:24-32 - The Reason For The Festival Of Purim

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 Esther came before the king, he commanded by letters that his wicked plot, which he devised against the Jews, should return upon his own head, and that he and his sons should be hanged on the gallows. ²⁶ Therefore they called these days Purim after the name of Pur. Therefore for all the words of this letter, and of that which they had seen concerning this matter, and which had come unto them, ²⁷ The Jews ordained, and took upon themselves, and upon their descendants, and upon all such as joined themselves unto them, so that it should not fail, that they would keep these two days according to what was written, and according to their 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 fall into disuse among the Jews, nor the memory of them perish from their descendants.

²⁹ Then Esther the queen, the daughter of Abihail, and Mordecai the Jew, wrote with all authority, to confirm this second letter about Purim. ³⁰ And he sent the letters unto all the Jews, to the hundred twenty and seven provinces of the kingdom of Ahasuerus, with words of peace and truth, ³¹ To confirm these days of Purim in their times appointed, according as Mordecai the Jew and Esther the queen had enjoined them, and as they had decreed for themselves and for their descendants, concerning the matters of the fastings and their lamentations. ³² And the decree of Esther confirmed these matters of Purim; and it was written in the book.
