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.
