Esther 9:23-32

And the Jews undertook to do as they had begun, and as Mordecai had written unto them; 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; but when the matter came before the king, he commanded by letters that his wicked device, which he had devised against the Jews, should return upon his own head, and that he and his sons should be hanged on the gallows. Wherefore they called these days Purim, after the name of 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 unto them, the Jews ordained, and took upon them, and upon their seed, and upon all such as joined themselves unto them, so that it should not fail, that they would keep these two days according to the writing thereof, and according to the appointed time thereof, every year; 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 the remembrance of them perish from their seed. Then Esther the queen, the daughter of Abihail, and Mordecai the Jew, wrote with all authority to confirm this second letter of Purim. And he sent letters unto all the Jews, to the hundred twenty and seven provinces of the kingdom of Ahasuerus, with words of peace and truth, to confirm these days of Purim in their appointed times, according as Mordecai the Jew and Esther the queen had enjoined them, and as they had ordained for themselves and for their seed, in the matter of the fastings and their cry. And the commandment of Esther confirmed these matters of Purim; and it was written in the book.
