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.
12. And Mordechai returned to the gate of the king. And Haman was propelled to his house mourning, and with a covered head.
It seems doubly strange for the verse to say Mordechai returned to the palace, when our commentary on the previous verse made clear the Haman found Mordechai in the house of study. According to the Talmud (Megillah 16a) and the Midrash (Esther Rabba 10:6), the verse emphasizes that Mordechai returned to the king’s gate instead of into because Mordechai returned to wearing sackcloth and fasting.
Rashi’s explaining that Mordechai returned to mourning seems to not be his pashut pshat, simple explanation.
The Maharsha clarifies that Mordechai could not enter the king’s gate wearing sackcloth because of their rules of propriety in those days, so he could only come as far as the gate, itself. Therefore, Mordechai, having been mourning in sackcloth for the last several days could not be said to be returning to a place where he could not have previously been.
R’ Avigdor Bonchek explains that being paraded on a horse emboldened Mordechai to defy Achashverosh’s law by going to gate in sackcloth.
The Targum writes that Mordechai returned to serving on the Sanhedrin at this point, a position that is described in TaNaCh (see Bireishis 19:1, Devarim 21:19, Ruth 4:1) as being positioned “at the gate.”
The Midrash (Shemos Rabba 38:4) teaches that the verse says Mordechai returned because he is humble. There is a humility in accepting one’s place, as is said of Avraham whom the Torah (Bireishis 18:33) describes as having “returned to his place” after speaking with H-Shem.
R’ Henoch Leibowitz notes that the Torah (Devarim 30:8) promises us that H-Shem will return us to our Land only after we suffer from our enemies. Rav Leibowitz explains that the lesson is that a person’s prayer in times of rescue should be equal in power and intensity to that with which one prays in times of troubles. The very purpose of our troubles is to increase our attachment to H-Shem. The proper method for this is to follow Rabbeinu Bachya’s advice (on Shemos 2:23) when he says that one’s prayer is the most intense in times of difficulty and that, therefore, it is incumbent on a person to remember that feeling of intensity, and bottle up that feeling of pain in order to pray strongly in the brighter future that the troubles do not return. At our most desperate, we should try to encapsulate the emotion to use in better times.
He quotes R’ Naftoli Tropp, the Rosh Yeshiva of the Chofetz Chaim’s yeshiva in Radin writes that a famous piyut said on Yom Kippur calls us all dalim, poor. Even the rich should recall that all is H-Shem’s and they only have their riches only by the grace of G-d.
The Yosef Lekach writes that Mordechai usually wore sackcloth during davening, and then changed for court. At this point, Mordechai did not change because he felt his prayers were unsuccessful, and not answered. This is because his riding on a horse did not manifestly spell out the redemption of the Jews. The Jews were still threatened.
Rebbetzin Heller points out that, being G-d focused, Mordechai didn’t care if Achashverosh loved or honored him. This event did not change Mordechai’s humility.
The Sfas Emes writes that Mordechai still felt guilty about causing the threat to Jewish existence by refusing to bow down to Haman. True teshuvah comes from the feeling of being unworthy of kindness from H-Shem. He concludes that one should never be too confident in this.
The Iyun Yaakov points out that, on the political side, Mordechai had anticipated using his saving Achashverosh’s life as leverage when begging Achashverosh to save the Jews – not just a pony ride around town. Disappointed by the loss of his ace in the hole, Mordechai’s only remaining means to save the Jews is to pray to H-Shem.
The Ohel Moshe quotes the Brisker Rav, R’ Yitzchak Zev HaLevi Soloveitchik that in his reporting the goings-on to Esther earlier (Esther 4:5-16), Mordechai was unwilling to get out of his sackcloth for even one moment and even requiring Hasach as an intermediary because prayer and emunah are the main tools for salvation.
The Ohel Moshe also brings R’ Yehonason Eibshutz who quotes the Talmud (Brachos 5b) that a prisoner does not free himself. Somebody else needs to help somebody out. Similarly, Mordechai, once he sees himself rescued, returned to pray for the other Jews. Similarly,
R’ Dovid Bleicher of Novordok notes that Mordechai had his own needs met, but kept praying for the Jews because he had worked on himself to feel as if he was still under the threat of death.
The Midrash (Esther Rabba 6:12) states that a true Jewish leader does not stop fasting until the prayers are answered.
The Maharal notes that Mordechai was not satisfied by this honor because Achasherosh did not come to thank him, himself. He had no reason to think that Achashverosh felt actual gratitude. After all, as R’ Elie Munk points out in his commentary on Chumash (Vayikra 7:30), of all the offerings, the only one which the Torah describes as having to be brought “by his own hands” is the shelamim (peace offering) because it is brought as a way to thank H-Shem, and “when expressing one’s gratitude, it is proper to do it personally.”
Parenthetically, he also quotes this as the reason brought by Abudraham for the congregation to say the blessing of Modim (thanksgiving) during the repetition of the Amidah prayer, since the congregational leader cannot express the gratitude of another person.
The Maharal also says in a few places (Nesivos Olam) that simcha (joy) comes from shleimus (completeness). Here, too, Mordechai cannot be content since the Jews are still under the threat of annihilation, and are thus incomplete.
Perhaps the simplest explanation to why Mordechai returned to his place can be gleaned from a story told about R’ Yechezkel Abramsky. While discussing Megillas Esther with his rebbetzin, he asked her what Mordechai could have been thinking while riding on the horse. She answered, “This type of foolishness is for drunkards. I wish this will be over soon, so I can return to learning Torah!”
