The document discusses chapter 9 of the Book of Esther. It summarizes that the chapter details Mordechai and Esther making the victory of the Jews over their enemies into an officially recognized Jewish holiday of Purim. It notes there is a significant digression in the middle that retells the story of Purim, but in a way that seems out of order and gives inconsistent reasons for the name of the holiday. The document raises questions about this puzzling section and says the next discussion will try to solve the "mystery of Esther's ninth chapter."
