According to R’ Chaim Kanievsky, the word, Purim, is written in full in this verse, as opposed to later (Esther 9:30), where it is written in a more incomplete form because on this particular first Purim, the Jews’ joy was boundless. Later, as the people were further removed from their miraculous salvation, their joy diminished accordingly.
The Vilna Gaon writes that the verse’s account of what the Jews “doing” refers to their feasting and joy, and it stresses that they did this on their own, without the need to be told to do so by Halachic rule.
כב כַּיָּמִים אֲשֶׁר–נָחוּ בָהֶם הַיְּהוּדִים מֵאוֹיְבֵיהֶם וְהַחֹדֶשׁ אֲשֶׁר נֶהְפַּךְ לָהֶם מִיָּגוֹן לְשִׂמְחָה וּמֵאֵבֶל לְיוֹם טוֹב לַעֲשׂוֹת אוֹתָם יְמֵי מִשְׁתֶּה וְשִׂמְחָה וּמִשְׁלוֹחַ מָנוֹת אִישׁ לְרֵעֵהוּ וּמַתָּנוֹת לָאֶבְיֹנִים
22. Like the days on which the Yehudim rested from their enemies and the month which was switched for them from sorrow to joy and from mourning to holiday to do on them days of feasting and joy and sending gifts each man to his fellow and gifts to the poverty-stricken.
- According to the Talmud Yerushalmi (Megillah 1:4), the verse uses the phrase “the month on which changed…” instead of explicitly using the name, Adar, because if Purim theoretically fell on Shabbos (as was possible before Hillel the Younger developed our calendar system), not to mix the rabbinic holiday of Purim with the Torah-level obligations of Shabbos. Although it would not push off our obligations on that day, they would be somewhat compromised. To emphasize that the important aspect of this is the month when this event occurred, the verse does not state the fact that it is Adar.
- Furthermore, the Talmud Yerushalmi (Megillah 1:1) also says that the entire month is fitting for Megillas Esther to be read publicly.
- The Vilna Gaon notes this is why the Talmud (Taanis 29a) famously says that when the month of Adar (and specifically not Purim) comes in, we increase our joy.
- The Ibn Ezra says that part of the reason for this is that sometimes Purim is not Adar, but rather in Adar Sheini. If the verse would have explicitly said Adar, Purim would have to be in the first Adar during leap years.
- The Maharal emphasizes that Haman was so overjoyed when the lot fell on Adar because it is the last month of the Jewish year, and has the spiritual potential to be an end, in the negative sense.
- R’ Chaim Kanievsky explains that the verse’s focus is on reversal because H-Shem can reverse anything, even those astrologically set “times.” After all, Haman’s choice of Adar as the month to attack the Jews was partially due to our supposed spiritual vulnerability.
- According to the Talmud Yerushalmi (Megillah 1:4), the verse stresses that the holiday would be celebrated “every year and year” to demonstrate that Purim will never be abolished, even in the time of Moshiach.
- R’ Yaakov Emden points out that these days were already established as days of joy. After all, Moshe Rabbeinu was born on the seventh of Adar, so his bris (“circumcision”) should have been scheduled for the 14th. However, the Talmud (Sotah 12a) says that he was born circumcised, so he only required a symbolic pin-prick called hatafas dam bris (Shulchan Aruch Yoreh Deah 262:1 and 264:1), and this procedure is not held on a Shabbos (Shulchan Aruch Yoreh Deah 260:2 and 263:1). Therefore, Moshe’s bris was on the 15th of Adar.
כ וַיִּכְתֹּב מָרְדֳּכַי אֶת–הַדְּבָרִים הָאֵלֶּה וַיִּשְׁלַח סְפָרִים אֶל–כָּל–הַיְּהוּדִים אֲשֶׁר בְּכָל–מְדִינוֹת הַמֶּלֶךְ אֲחַשְׁוֵרוֹשׁ הַקְּרוֹבִים וְהָרְחוֹקִים
20. And Mordechai wrote these things and sent books to all of the Yehudim in all of the states of King Achashverosh, the near and the far.
- Malbim says that what Mordechai wrote were the details of what occurred, since he was concerned that Jews outside of Shushan knew very little about the miraculous success of the Jews of Shushan.
- According to Rashi, what Mordechai wrote is the content of Megillas Esther, exactly as it appears today.
- The Ibn Ezra wrote down the reason for the previously mentioned joy.
- Pirkei d’Rebbe Eliezer writes that Mordechai wrote this down as the head of the Sanhedrin.
- The Vilna Gaon explains that this means that he wrote the Halachic details of how to properly commemorate Purim, with what can and cannot be done on this day.
- R’ Dovid Feinstein emphasizes that Mordechai is making the changes for the holiday that the Jews had accepted upon themselves spontaneously.
- R’ Elisha Gallico notes that it is so important to remember the real source of Purim, there are two readings of Megillas Esther every Purim. This is why Moredechai did not make Purim an actual Yom Tov in order to allow the Jews to perform the other mitzvos of the day.
- The Oznei Yehoshua notes that if we had Purim without its rules, we would end up having an empty, meaningless holiday. As it stands, Purim is the epitome of giving in the Jewish community.
- The Talmud (Megillah 5b) explains each of the different expressions for this holiday to mean a different method for celebrating the day. Simcha (“joy”) is interpreted as not giving eulogies (in the event of a death); v’mishteh (“and feasting”) is interpreted as prohibiting fasting; and v’yom tov (“and the holiday”) is interpreted as prohibiting work on Purim. Later, the Talmud (Megillah 7a) interprets the phrase mishloach manos (“sending gifts”) as the requirement to send through a messenger at least two kinds of food to at least one friend.
- The Rambam (Mishneh Torah, Hilchos Megillah 2:15) writes that even two poor people are required to send another poor person some food to fulfill their obligations.
- The Trumas HaDeshen writes that the exchange of food is intended to make sure everyone has enough for the feast.
- M’nos HaLevi writes that we send gifts to promote friendship because achdus (“unity”) rescued the Jews.
- The Midrash HaGadol on Devarim points out that this demonstrates the greatness of chesed because we were rescued because of it.
- Ginzei HaMelech writes that we use a messenger because this shows achdus (“unity”) in requiring another person to get involved in this mitzva. Similarly, he points out, this is why Megillas Esther always uses Yehudim for Jews, since the root of that word is echad, one. Furthermore, the giving of gifts through messengers acts as an additional tikkun for Yaakov’s giving gifts (Bireishis 32:14-17) to Eisav, the ancestor of Amalek, through messengers.
- The Vilna Gaon and Midrash Shmuel note that the Jews’ celebrating in this way parallels the three parts of Haman’s plan (Esther 3:13); the joy serves to counteract Haman’s plan to destroy the Jews, the feasting serves to counteract Haman’s plan to kill the Jews, and the Yom Tov serves to counteract Haman’s plan to annihilate the Jews.
- The Vilna Gaon writes that, eventually, Purim was not accepted as a full Yom Tov because that would keep people from performing the other mitzvos of Purim.
- The Ran notes that there is a concept (Bamidbar 15:16) that there is one Torah and one law for all Jews. In other words, there should ordinarily be only one day for all Jews to celebrate together. For this reason, Mendel Weinbach notes, usually, according to Halacha (Mishna Berura 688:12), where one spends Purim determines when one will celebrate it. For example, a Jew visiting a walled city temporarily nevertheless celebrates it there for purposes of achdus (“unity”).
- R’ Betzalel haKohen of Vilna, however, writes that this distinction is meant to stress that Purim is a d’rabbanan (“rabbinic”) holiday, since the Torah’s (Devarim 13:1) prohibition to add to the given mitzvos only applies to d’oraisa (“Scriptural”) laws.
- A story is told of a visitor from Bnei Brak in the home of R’ Shlomo Bloch in Yerushalayim. R’ Bloch invited him to drink at his Purim feast (on Shushan Purim), but since he had already drunk the previous day, the visitor argued that he had already fulfilled the mitzva of drinking on Purim. R’ Bloch retorted, “You may have fulfilled Purim, but you can still fulfill the mitzva of feeling another Jew’s joy.”
- The Chasam Sofer gives another reason to have two days of Purim – to avoid bitul Torah. Since the Mishna (Avos 1:2) teaches that Torah is one of the three foundations upon which the world stands, if there were (chas v’Shalom) one moment when nobody was learning Torah, the world would cease to exist immediately. With the advent of Shushan Purim, while one group is drinking and celebrating, the other group can uphold the world by learning.
