פירוש על מגילה 27:22

The parable of Ahasuerus and Haman, etc.: Meaning to say [that] it can be learned from Ahasuerus, that it was also his intention to destroy them.

(To return them) to the right way: As they decreed fasts upon them, for repentance - as it is written (Esther 4:3), "fasting, weeping, and wailing, and everybody lay in sackcloth and ashes."

Except for the reading of the Megillah (Scroll of Esther): But perhaps you will say, [also] the light of Channukah! [However,] the prophets had already ceased. Whereas in the days of Mordechai, there was Chaggai, Zechariah and Malakhi (they were still alive).

From slavery to freedom: With the exodus from Egypt, they recited the song at the sea.

Let us also recite Hallel: As it is song.

We teach this version - Rava said, "Granted there, etc. and not servants of Pharaoh": For behold, they went out to freedom.

We were still the servants of Ahasuerus: As they were only saved from death.

Both according to Rava who said this is why we do not say Hallel, as we were still the servants of Ahasuerus - then if not for that, we would say it -

As well as according to Rav Naḥman who said [that] the reading of the Scroll is in place of Hallel.

All the other lands were [not] fit for song over the miracle that occurred to them.
