- The Vilna Gaon writes that the verse’s account of the Jews “doing what Mordechai wrote” refers to their giving charity and gifts.
- Malbim explains that those Jews residing in the walled cities did not start to celebrate on their own, but only began when Mordechai’s decree went out.
- M’nos HaLevi notes again that by writing it down, Mordechai retroactively transformed the Jews’ voluntary actions into the obligatory mitzvos of Purim.
- R’ Dovid Feinstein adds that although the celebrations of Purim started on the Jews’ initiative, they submitted to the rule (and changes) of the sages.
- The Dena Pishra writes that, at first, the Jews were upset with Mordechai for not bowing down to Haman (Esther 3:2), but now they recognized the wisdom behind Mordechai’s actions.
- R’ Dovid Moshe Valle also points out that the Jews realized now that Mordechai had Ruach HaKodesh because he was able to summarize the events they witnessed into this multi-level text we have before us.
יט עַל–כֵּן הַיְּהוּדִים הַפְּרָוזִים [הַפְּרָזִים] הַיּשְׁבִים בְּעָרֵי הַפְּרָזוֹת עֹשִׂים אֵת יוֹם אַרְבָּעָה עָשָׂר לְחֹדֶשׁ אֲדָר שִׂמְחָה וּמִשְׁתֶּה וְיוֹם טוֹב וּמִשְׁלוֹחַ מָנוֹת אִישׁ לְרֵעֵהוּ
19. Therefore, the unfortified Yehudim in the unfortified cities made the fourteenth day of the month of Adar [a day of] joy, feasting, and holiday, and from sending gifts a man to his fellow.
- According to Rashi, quoting the Talmud (Megillah 2b) “unfortified cities” are those that were not surrounded by walls in the days of Yehoshua.
- The Ziv HaMinhagim writes that this definitely includes only Yerushalayim. There is a doubt regarding Ashdod, Ashkelon, Beit Sha’an, Gush Khaloav, Hebron, Haifa, Tiberias, Jaffa, Lod, Gaza, Acco, Safed, Ramleh, and Shechem.
- R’ Ovadya of Bartenura explains that the times of Yehoshua are the reference point for the definition of walled cities in order to remind us of the root hatred of Amalek is their attacking us when we were leaving Mitrzrayim, when they battled Yehoshua.
- The Sfas Emes adds that, by recalling Yerushalayim, we remember that the purpose of Purim was the rebuilding of the Beis HaMikdash.
