- The Maharal explains that, on a simple level, the “statement” is attributed to Esther to emphasize that her status as queen of Persia aided in Purim’s being accepted.
- Furthermore, Kedushas Levi points out that Esther actually argued with the Sages who wanted Purim on Nisan 16, since that was the actual day when Achashverosh punished Haman, and put an end to his plot. She argued that if Purim will then remain on the same day as Pesach, it would not be as obvious, and will end up being forgotten.
- R’ Yehonason Eibshutz notes that her self sacrifice is the reason for Esther’s being credited with the holiday and book in TaNaCh.
- The Ben Ish Chai finds an allusion to this in “Eishis Chayil,” Shlomo haMelech’s praise of great women. The verse there (Mishlei 31:31), the gematria of yadeha (“her hand”) can be broken up into yad (10+4=14) and eha (10+5=15), alluding to the 14th and 15th of the month of Adar, both established by Esther’s hand.
- In the view of the Ohel Moshe, by the verse using the word vatich’tov (“and she wrote”), which is a singular, feminine verb, it intends to emphasize Esther’s role because she risked her life approaching Achashverosh (Esther 4:16) in order to save the Jewish people1.
- The Ginzei HaMelech wonders why Megillas Esther is attributed to Esther if both she and Mordechai co-authored the work. He suggests that Esther deserves the bulk of the credit because the Talmud (Megilla 7a) records how Esther insisted on Purim’s perpetuity, arguing with the reluctant Sages about writing this book to remember her “for generations.” This is why Megillas Esther is attributed to her.
- According to the Alshich, another reason why Megillas Esther is attributed to Esther is because it was her idea (Esther 5:4) to have the series of feasts in which she finally accused Haman of his perfidy. to stress that all was ultimately accomplished through the power of prayer.
- Esther thus added to the text, as the Ginzei HaMelech makes clear, an emphasis of the actions over the events.
- Furthermore, as R’ Eliyahu Dessler writes, the very fact that Esther began Megillas Esther with the Achashverosh’s feast over a decade before Haman’s decree shows that the threat to our existence started then, as the Jews’ Sages like Mordechai were warning at the time.
1Similarly R’ Chaim Shmulevitz writes in Sichos Mussar (Vayikra) that the name the Torah uses for Moshe out of the ten alternatives listed in the Midrash (Vayikra Rabba 1:3) is meant to emphasize the mesiras nefesh (“self-sacrifice”) of Basya, the daughter of Pharaoh, who gave him that name.
