Mishnayos Megillah Perek 1 Mishnah 1

מגילה נקראת באחד עשר בשנים עשר – at times on this [day] and at times on that [day] as is explained further on.

מימות יהושע בן נון קורין בט"ו – as it is written (Esther 9:19): “That is why village Jews, who live in unwalled towns observe the fourteenth day of the month of Adar…” And when those in unwalled towns [read the Megillah] on the fourteenth [of Adar], we infer from it that those are in walled cities read on the fifteenth [of Adar]. And this is from the time of Joshua [son of Nun], which we derive by analogy from [the usage of the words] פרזי פרזי . It is written here (Esther 9:19): “village Jews” and it is written there (Deuteronomy 3:5): “…apart from a great number of unwalled towns.” Just as there, [it is] from the time of Joshua, so here too, [it is] from the time of Joshua. And they established that cities surrounded by a wall from the days of Joshua, even though they now lack a wall , should read [the Megillah] on the fifteenth [of Adar] like Shushan/Susa, in order to distribute honor to the Land of Israel that was destroyed during the days of Mordecai and Esther, in order that they [residents in the Land of Israel] would read [the Megillah] like those who live in Shushan and would be considered as if they are walled cities, even though right now they are destroyed. And there would be a reminder to the Land of Israel through this miracle, and since Joshua began to fight with the Amalekites first, as it is written (Exodus 17:14): “[Then the LORD said to Moses,] ‘Inscribe this in a document as a reminder to the, and read it aloud to Joshua: [I will utterly blot out the memory of Amalek from under heaven]!’” Therefore, they mention it [Amalek – the ancestors of Haman] from the days of Joshua.

אלא שהכפרים מקדימין – that is to say, in the aftermath that, those [who live] in walled cities read [the Megillah] on the fifteenth [of Adar] and those who are not in walled cities [read] on the fourteenth [of Adar], everyone is within this principle. So how do we find further [that one can read the Megillah] on the eleventh, the twelfth or on the thirteenth [of Adar]? Rather, those who dwell in villages were given permission to advance their reading to the gathering [i.e., market] day [prior to Purim], on the Monday of the week before the fourteenth [of the month] or the Thursday of the week [before the fourteenth] , which are the gathering day, when the villagers gather together in the villages for judgment, since the Jewish courts sit on Mondays and Thursdays according to the ordinance of Ezra [the Scribe]. Alternatively, the villagers gather together in the cities [that are unwalled] on Mondays and Thursdays to hear the reading of the Torah. But the villagers are not so expert to read [the Torah] and need that it should be read for them by one of the city-dwellers. And the Sages did not trouble them to return and come on the fourteenth [of Adar], in order that they would be free on Purim day to provide for the needs of the festive Purim meal to those who dwell in the cities. And they [the Sages] found a hint for this from the Bible, as it is written (Esther 9:31): “These days of Purim shall be observed at their proper time[s, as Mordecai the Jew – and now Queen Esther – has obligated them to do…” and if Mordecai and Esther had not established anything other than the fourteenth and fifteenth [of Adar] which is written in the Bible, let the verse say, “in their time.” What is the meaning of “at their proper time[s]?” We learn from it two other times/occasions other than those that are written in the Megillah; but it was not necessary for the Bible to include the thirteenth [of Adar] as a day appropriate for reading [the Megillah] since the essence of the miracle [of Purim] was on that day, since on it they [i.e., the Jews] gathered to be avenged of their enemies, whether in Shushan or in the rest of the [one-hundred and twenty-seven] provinces. By force, the Bible only had to include the eleventh and the twelfth [of Adar], and we don’t say that it includes the sixteenth and seventeenth [of Adar] for after the fourteen and fifteenth [of Adar] mentioned in the Megillah, as the Bible states (Esther 9:27): “[to observe these two days] in the manner prescribed/ולא יעבור [and at the proper time each year].”
