Maamar Mordechai points out that, when the Jews were in Egypt, the ten plagues occurred for one month each. That being the case, the second to last plague, that of darkness, happened one month before Passover, which would mean it fell in Adar. Haman assumed the darkness was a plague that hurt the Jews since so many of them died then (see Rashi to Shemos 10:22 and 13:18). After all, four fifths of the Jews died in Egypt because they did not believe in their upcoming rescue. H-Shem killed these unfortunates during the plague of darkness to avoid the Egyptians seeing this, and assuming the Jews’ G-d is no longer with them.1 The Jews in Persia, by attending Achashverosh’s party, indicated that they, too, lost faith in their redemption, and this is why the lots falling on Adar so pleased Haman.
Adar is also the month when Moshe died. According to the Talmud (Megillah 13b), Haman knew this because it is so written in the end of Devarim (34:8) and can be calculated from the book of Yehoshua. According to our tradition, the seventh of Adar, his date of death, is also his date of birth. Rabbi Mendel Weinbach writes that Haman did not know this because, as opposed to his date of birth, his date of death is only found in the Oral Torah.
The Abudraham calculates that Adar 13 would mark the end of the seven-day mourning period (shiva) for Moshe. According to the Maharsha, that seven-day period of mourning continues in some mystical way the merits of the mourned. After that point, the dead only receive merit of others step up to take over their spiritual roles. Interestingly, Rabbi Dovid Feinstein notes that, Moshe having been born on 7 Adar, his bris (circumcision) would have been on 14 Adar, Purim!2
1It bespeaks a certain callousness that the Egyptians seemed not to notice the sudden disappearance of several million people.
2However, since Moshe was born complete and circumcised (Talmud, Sotah 12a), his bris would only require a symbolic pin-prick of blood called “hatafas dam bris” (Shulchan Aruch Yoreh Deah 262:1 and 264:1), and this procedure would not be help on a Shabbos (Shulchan Aruch Yoreh Deah 260:2 and 263:1). Therefore, Moshe’s symbolic bris was held on the following day, Shushan Purim.
Mordechai would not listen to their attempts to convince his to bow to Haman. This seems to imply that they attempted to help him change. However, that does not necessarily mean that they were righteous. According to the Talmud (Niddah 61a), Og also told Avram of the threat to his nephew Lot’s life (Bireishis 14:13) for his own desire to see Avram die and make his wife Sarai available for himself. Despite his evil intentions, the Midrash (Bireishis Rabbah 42:8) teaches that Og is nevertheless rewarded. These servants, too, may have had their own motivation in Mordechai’s conforming to their behavior.
13. And the king said to the wise men who know the times – since such is the way of the king before all those who know knowledge and justice.
According to the Talmud (Megillah 12b), the wise men whom the king approached after being insulted by his wife were none other than the Jewish Sages. The idea that they “know the times” means that our Sages are in control of the times and can have a hand in the calendar by, for instance, adding a thirteenth month (Adar Sheini) by declaring a leap year when necessary to balance the lunar months with the solar seasons (see Talmud, Sanhedrin 11b). Relevant to Tu B’Shvat this week, in the laws of orlah, a tree’s fruit cannot be eaten during the first three years of its life (Vayikra 19:23). The Sages’ ability to mandate a thirteenth month forces a farmer to wait an entire month longer for a tree to turn three years-old. We allude to this rabbinic power in our prayers. In the Musaf prayer of Shabbos (a day which cannot be set by the Sages) we say, “Blessed are You, H-Shem, Who sanctified the Shabbos,” whereas in the Musaf prayer of a Yom Tov (a day which can be set by the Sages) we say “Blessed are You, H-Shem, Who sanctified Israel and the times,” alluding to the fact that Israel can affect the calendar. Both the Ibn Ezra and Rav Dovid Feinstein add that, on a more mystical plane, the Sages were equally aware of astrology and which times have which spiritual energies (and how best to use these) as learned from Sefer Yetzira (Chapter 5).1
Rav Yehonoson Eibshutz writes that Achashverosh was hoping that the Sages, knowing these spiritual times as they do, would find that Vashti’s mazal (cosmic, spiritual influence) would allow her to live.
On a practical level, the Ben Ish Chai writes that the Sages could find ways to excuse any crime. For reasons too complex to explain here2, they were trained to do so because a unanimous decision would expatiate a perpetrator. In order to find a way to discredit a given exhibit of evidence, the Sages needed to then be completely aware of situations to best judge them.
As the Malbim writes, the Sages knew best how to apply laws to situations. The Maharal adds that a Sage, a righteous person by definition, always knows how to act under a given situation.
According to the Talmud (ibid.) the Sages found a way to not give advice because they realized that they were in a bind, a Catch-22. On the one hand, telling him to kill her as is expected of an insulted monarch may backfire and cause more Jew-hatred. On the other hand, sparing her meant subjecting Jewish women to untold humiliation under Vashti’s evil hands. To get out of having to give advice in this matter, the Sages simply pointed out that they could not judge capital cases ever since the Temple was destroyed. Rabbi Moshe Meir Weiss reminds us that one of the recurring themes of Megillas Esther is mida kineged mida, measure for measure. Here, Vashti’s halting the rebuilding of the Beis Hamikdash effectively ended her own life. Had there been a Temple, and it accompanying Sanhedrin, the Sages would have been able to pardon her.
1 My Rosh Yeshiva, Rav Yisroel Simcha Schorr, shlita, would often remind us that Pesach came before the exodus from Egypt. The time, itself, had the strength needed for an exodus. This is why Lot offered matzos to his visiting angels in Nisan (Bireishis 19:3, see Rashi there) before there was even an exodus to obligate the eating of matza. From the time of Creation, that time had the spiritual energy to be a vehicle for the Egyptian exodus.
2See Talmud (Sanhedrin 17a) for the details of this rule.
Several reasons are given for the Megillah’s stressing the participants’ being “from great to small.” After all, like celebrities entering an awards ceremony or the grand finale in a fireworks show, the people of greater stature are usually honored after those of lower stature according to propriety. Furthermore, in the story of Lot, the Sodomites are described as attacking his home “from the young to the old” (Bereishis 19:4). The Sfas Emes posits that the phraseology suggests that even minors were allowed at the party. According to the Malbim and Rav Eliezer Ashkenazi, the mixed-up order allows for comparison, which implies that Achashverosh was telling his more noble guests that they were now all equal with everyone else – making everyone mere slaves to him. Sometimes, as in George Orwell’s Animal Farm, being equal means that everyone is less than they deserve.
