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

²⁴ how that Haman, the son of Hammedatha all the Jews' enemy, had devised to destroy all the Jews, and caused to cast Pur, that is lot, for to put them in fear, and to bring them to naught: ²⁵ and how Esther went and spake to the king, that through letters his wicked device - which he imagined against the Jews - might be turned upon his own head, and how he and his sons were hanged on the tree. ²⁶ For the which cause they called this day Purim after the name of Pur, according to all the words of this writing: and what they themselves had seen, and what had happened unto them. ²⁷ And the Jews set it up, and took it upon them and their seed, and upon all such as joined themselves unto them, that they would not miss to observe these two days yearly, according as they were written and appointed; ²⁸ how that these days are not to be forgotten, but to be kept of the children's children among all kindreds in all lands and cities. They are the days of Purim, which are not to be overslipped among the Jews, and the memorial of them ought not to perish from their seed.

²⁹ And queen Esther the daughter of Abihail and Mordecai the Jew wrote with all authority, to confirm this second writing of Purim, ³⁰ and sent the letters unto all the Jews, in the hundred and seven and twenty lands of the empire of Ahasuerus, with friendly and faithful words, ³¹ to confirm these days of Purim, in their time appointed, according as Mordecai the Jew and Esther the queen had ordained concerning them: like as they upon their soul and upon their seed had confirmed the acts of the fasting and of her complaint. ³² And Esther commanded to establish these acts of this Purim, and to write them in a book.
