The Me’am Loez writes that they decided on the name of the holiday being Purim because the lots being rolled in Nissan, and coming up with the date in Adar eleven months later gave the Jews time to pray and to repent.
Furthermore, Adar had previously had no other holidays, so Purim’s falling out then made it stand out more conspicuously as a holiday, receiving the attention it deserves.
Also, the Vilna Gaon and Malbim point out that the lots pointed to a potentially bad fortune, but H-Shem reversed it to a good fortune.
In quoting Rabbeinu Yona’s Shaarei Teshuva (2:4), the Ginzei HaMelech notes that just as sin can be transformed to a mitzva status if the sin leads to teshuva (“repentance”), so too the lots lead directly to the Jews’ redemption.
The Ksav Sofer supports this point by writing that in calling the day Purim, we celebrate the pain suffered by the Jews at this time, since it led directly to their re-acceptance of Torah (Esther 9:27).
Rav Moshe Feinstein wrote that the message to be learned from this is that one should never overconfident of one’s “lot,” thinking that one’s greatness in Torah knowledge or observance will necessarily parry off the Evil Inclination. Rather, even such a person should be always mindful of one’s potential to fall prey to one’s natural, animalistic urges.
The Alshich writes that by stressing that Haman hates all the Yehudim, Mordechai was making it amply clear that Haman’s hate was not just a personal vendetta against him. Indeed, as noted earlier, he hated all Jews.
In that sense, according to the Me’am Loez, Haman was worse than Pharaoh; whereas Haman (Esther 3:13) wanted to kill all of the Jews, Pharaoh (Shemos 1:16) wanted to kill male Jews only.
R’ Meir Simcha of Dvinsk notes that, historically, hatred of Jews escalates when they ignore their faith.
As the Rosh Yeshivah of Brisk, R’ Meshulam Dovid Soloveitchik, explains, Haman hated all Jews, regardless of the efforts of some to conform to his whims in an effort to befriend him, like those Jews who attended Achashverosh’s feast against the advice of their contemporary sages.
In his introductory comments on the Talmudic tractate Megillah, the Ramban explains that the idea behind sending the books near and far means that they were sent through the entire expanse – from Hodu to Cush (Esther 1:1) – of Achashverosh’s kingdom.
Me’am Loez suggests that they were even sent to other countries.
The Dena Pishra explains that since Mordechai’s goal was to create a feeling of achdus (“unity”), he even wanted to reach those Jews whose lack of faith and subsequent fear motivated them to flea battle.
Rav Schwab, however, understands “close” as those Jews who were living in Shushan and celebrating on the 14th of Adar, whereas “far” refers to those Jews who returned to Eretz Yisroel and celebrated Shushan Purim on the 15th of Adar in the only place where one must certainly do so – the holy city of Yerushalayim.
The Sha’ar Yissachar writes that the books were sent near and far so no Jew could ever devise the excuse that they are too far from holiness. Rather, the near and far have equal access to the holiness that emanates from Purim.
Keser Shem Tov quotes that Talmudic (Megillah 17a) rule that Megillas Esther on Purim must be read as written, and not backwards. The Keser Shem Tov then wonders why anybody would think to read it backwards. He posits that the Talmud means that nobody should ever consider the Purim story as some ancient, historic event without real relevance to our lives.
The Talmud (Megillah 7a) notes that one of the proofs that Megillas Esther was written with ruach hakodesh (see Introduction) is that no human writer could possibly know that the Jews did not take any spoils.
Rashi writes that the Jews had rights to the spoils, but decided to wave those rights, and give the spoils to the king in order to maintain friendly relations with the palace.
The Dena Pishra writes that they did not take spoils because they did not want others to think that the Jews’ motivation was financial.
In M’aarchei Lev, Rav Moshe Schwab writes that since this was the property of Amalek, it was forbidden to take, as was the case for Shaul (Shmuel 1 15:3). and this is why the Jews refrained from doing so here.
In fact, the Binyan Ariel and Nachal Eshkol write that the Jews’ self-control in this incident was a tikun for the sin of Shaul in sparing (Shmuel 1 15:9) Amalek’s property.
Interestingly, the M’lo HaOmer and Me’am Loez both note that the initial letters of the ninth, tenth, eleventh and twelfth words of this verse, uvabeeza lo shalchu es (“and from their spoils they did not send”) can be rearranged to spell Shaul.
The Sfas Emes writes that the Jews took the spoils, but destroyed them in an effort to not benefit from the property.
However, R’ Yitzchak Yeruchem Diskin writes in Ohelim that Jews have an obligation to take the property of Amalek and destroy it, but did not do so here. The reason was that the Talmud (Megillah 16a) considers Haman to have been a slave. As such, he relinquished all rights to personal belongings. This includes his children. This also answers the question of how his grandchildren could study Torah in Bnei Brak if Amalek is never allowed to join the Jewish people. Such is not the case for his grandchildren because of his status of being a slave.
Megillas Seris adds another reason they did not take the spoils – they only had one day to kill Amalek, and they did not want to run the risk of missing the opportunity to fulfill this mitzva. In the course of performing a mitzva, they totally ignored anything ancillary to killing out their enemies.
The Gerrer Rebbe notes that matanos la’evyonim, the Halachic (Shulchan Aruch Orach Chaim 695:4) injunction to donate to the poor on Purim is in honor of the impoverished Jews of the time not taking the spoils of their enemies, despite their needs.
