According to the Vilna Gaon, Esther requested that Haman’s sons be hanged to make it clear that the Jews were acting in accordance with the will of the king, avoiding any future persecution. By hanging Haman’s sons, it was sign to everyone that the king approved of the Jews’ actions.
Ohel Moshe writes that the people could have theoretically thought that Haman was hanged for attempting to kill Mordechai, the rescuer of the king. Esther wanted it to be very clear that, in actual fact, for generations that this was not some political soap opera, but rather H-Shem did all of this for the sake of the Jews.
R’ Yehonason Eibshutz similarly demonstrates that it is not from Achashverosh, but from H-Shem.
Interestingly, Yalkut Pisron Torah (273) writes that this group of sons were handed over to the Jews in the merit of the Jews’ keeping the mitzva (Devarim 22:6-7) of shiluach hakan (“chasing away the mother bird”).
In the Parsha of Titzaveh, which is usually read before Purim, in the first verse (Shemos 27:20), H-Shem commands the Jewish people to make the clothing of the kohanim using the words, “es bnei Yisroel v’yik’chu.” Rabbi Yosef Freedman points out that the last letters of those four words can be rearranged to spell talui (“hanging”) and the first letters of the same words can be rearranged to spell av v’yud (“the father and ten”).
R’ Moshe Dovid Valle notes that the ten sons of Haman, and Haman himself, hang on the tree together, and those eleven people parallel the eleven1 curses mentioned in the Torah (Devarim 27:15-26) reserved for those who do not keep H-Shem’s Law. Their hanging should remove from us these curses.
Rabbi Yaakov Asher Sinclair (https://ohr.edu/purim/deeper_insights/3440) writes that these dead bodies needed to be hanged because the Talmud (Sanhedrin 97b) promises that Moshiach will come to the Jews even if they do not deserve him. This will occur after a wave of teshuva (“repentance”) takes us over after the evil decrees of a tyrant worse than Haman, himself.
together, there are twelve curses in those verses, not eleven. See
Rashi there (Devarim 27:26) that the twelfth and final of these
curses is a general one that encompasses the entire Torah. Perhaps
this is a reason for R’ Moshe Dovid Valle to have not included it in
his calculation of the number of curses.
The Maamar Mordechai writes that Esther mentions the Jews of Shushan specifically because they had been under the threat of annihilation the earliest, and had knowingly been suffering under the shadow of death all of this time. It was only fair for them to reap the benefits of the victory first.
As understood by Rabbi Jonathan Taub, Malbim notes that this is first time for the remainder of Megillas Esther that Shushan is not called Shushan HaBirah (which he translates as the palace compound). He answers that Esther wanted permission to kill in the city as they had in the palace.
In a very different perspective, R’ Shimon Schwab writes that the verse mentions Shushan specifically because the Jews only killed there because they were afraid elsewhere. Esther wanted to show that faith is the thing that helps them. When the Jews do their part, H-Shem will do His part. He continues that this lack of faith is the reason for a Shushan Purim – it is a sign that the Jews in Shushan did not deserve to join the Jews in celebration on the same day.
The Ben Ish Chai points out that Shushan (300+6+300+50=656) has the same gematria (and even same letters) as sason (“joy”) (300+300+6+50=656), which is what the Jews experienced (Esther 8:16) upon their miraculous rescue from obliteration.
Furthermore, it is also the same gematria as lashon ra (“evil speech”) (30+300+6+50+200+70=656). Evil speech is what Haman tried to use (Esther 3:8) to defame the Jews before Achashverosh when requesting permission to exterminate them.
13. And Esther said, “If it is good for the king, give also tomorrow to the Yehudim who are in Shusham to do according to today’s law, and the sons of Haman hang on the tree.”
In a move reminiscent of her request (Esther 5:8) for a second party (also requesting it for “tomorrow!”), given the opportunity to ask of anything from the king, Esther asks for a seeming repeat of the previous day.
M’nos HaLevi explains that this would give the opportunity to kill more of the Jews’ enemies, avoiding the possibility of their getting revenge.
According to the Ben Ish Chai, Esther wanted two days to mirror the two days Haman planned in his decree – one day to kill off the people, and the second day to take their belongings.
The Megillas Sesarim notes that the Jewish court met in Shushan, as is evident from the fact that Mordechai (who was on the court) lived there, and the Talmud (Megillah 12a) says Achashverosh consulted the Jewish scholars regarding Vashti’s behavior. That being the case, the Shechina had some influence in Shushan since the Talmud (Brachos 6a) teaches that the Shechina resides where a Jewish court judges. Esther felt that the Shechina left as soon as Haman made the decree to kill the Jews. The second day was intended to allow for the Shechina to return.
The Ginzei HaMelech posits that Esther requested a second day to effect a tikkun for the mistake of Shaul in letting Agag live. He quotes the Pachad Yitzchak, who writes that there were previously two wars with Amalek, a defensive one when they attacked in the time of Moshe (Shemos 17:8-16), and an offensive battle in which H-Shem commanded their eradication in the time of Shaul (Shmuel 1 15:1-9). The first day symbolizes that first war because it was also defensive. The requested second day would represent the second, offensive, war. He adds that since the word, melech also represents H-Shem, Esther is asking the Creator for a future (as Rashi defines machar (“tomorrow”)) directive to destroy Amalek, in the days of Moshiach.
Rav Shlomo Brevda (zt”l) writes that Esther asked for a second day so that people would not say that Haman’s erred in his interpretation of astrology in choosing the 13th of Adar. Esther wanted it to be crystal clear that, although Haman’s astrological skills were perfectly accurate, H-Shem changed the decree to save the Jews.
d’Rebbe Eliezer (50) as explained by Peirush Maharzav, uses this
verse’s mention of Haman’s ten sons, as well as three other mentions
(Esther 9:10, 9:13, and 9:14) of his ten sons, to suggest that Haman
had a total of forty sons, or ten times four.
12. And the king said to Esther the Queen, “In Shushan the capital, the Yehudim killed and destroyed five hundred man and the ten sons of Haman. In the remaining states of the king, what did they do? What do you ask and it will be given you. And what do you request more and it will be done.”
In the first half of this verse, the tone seems to imply that Achashverosh was upset about the casualties. In fact, the Midrash Lekach Tov writes that Achashverosh was actually upset about his dead citizens, but H-Shem controls leaders, as the verse (Mishlei 21:1) teaches that the hearts of kings are in the Hands of H-Shem.
R’ Dovid Feinstein points out that the tone of the second half of the verse certainly sounds as though Achashverosh seems unaffected by this loss of life.
The Talmud (Megillah 16b) describes this sudden change of heart as an angel “slapping him on his lips.”
R’ Mendel Weinbach suggests that such a slap has this effect because Achashverosh suddenly felt Heaven did not want him speaking in an upset manner toward Esther. It literally hurt to speak the way he had been.
Interestingly, the Midrash (Bireishis Rabba 92:7) notes this verse as one of ten kal v’chomer (“a fortiori”) arguments in TaNaCh. In other words, if the Jews killed 500 people in Shushan, how much more likely did they kill more elsewhere!
In fact, the Alshich points out that Achashverosh must have been thinking that if so many were killed in Shushan – where the informed public was ready for a fight – how much more-so in other parts of the kingdom!
On the other hand, the M’nos HaLevi quotes R’ Gakon’s opinion that the bloodthirsty Achashverosh was disappointed that such a relatively small number of his people were killed after the Jews had from Pesach until Adar 13th to prepare for battle. This is why he asked if he could do more to help.
Malbim explains that Achashverosh did not know there would be so many Jew-haters. From a place of genuine concern, he offers Esther more help.
According to Malbim, the Jews provided Achashverosh with a count of the dead in order to demonstrate to the king that the very existence of these 500 major enemies of the Jews implied the existence of countless more minor enemies.
The Yad HaMelech sees in this accounting the Jews’ report to the king of how many spoils were not touched.
The Maamar Mordechai points out that Achashverosh – having risen to the top of Persian society as a military leader – would have enjoyed hearing these numbers of military casualties and exploits.
It is the opinion of Rav Galico, however, that the fatalities were reported to Achashverosh by the enemies of the Jews in order to anger Achashverosh. It was yet another minor miracle that he did not become upset.
11.On that day, the count of the killed in Shushan the capital came before the king.
to Yosef Lekach, the verse stresses that this occurred on that day
because Mordechai told Jews to stop the killing in the afternoon,
although they had permission for the entire day. This was done in
order to show that we are not blood-thirsty. This is the reason they
were given an extra day.
