(32) In the book.--It is doubtful what "the book" here means. The Vulgate explains it of the Book of Esther itself, and so many modern scholars. Still "the book" hardly seems a natural Hebrew way of referring to a work on the part of its author as he writes it, and no similar case is adducible. Others think it must have been a book written at the time on the subject of the festival, which is, perhaps, possible. Canon Rawlinson identifies it with "the Book of the Chronicles of the Kings of Media and Persia." Because such is the use of the word book elsewhere in Esther.

Verse 32. - The decree of Esther. Rather, "a commandment of Esther." Some fresh act seems to be intended - something beyond the joint letter of Esther and Mordecai; though why it was needed, or what additional authority it could give, is not apparent. And it was written in the book. i.e. "this commandment of Esther was inserted in the book of the chronicles," where the writer probably found it. No other book being mentioned in Esther but this, "the book" can have no other meaning (see Esther 2:23; Esther 6:1; Esther 10:2).

9:20-32 The observance of the Jewish feasts, is a public declaration of the truth of the Old Testament Scriptures. And as the Old Testament Scriptures are true, the Messiah expected by the Jews is come long ago; and none but Jesus of Nazareth can be that Messiah. The festival was appointed by authority, yet under the direction of the Spirit of God. It was called the feast of Purim, from a Persian word, which signifies a lot. The name of this festival would remind them of the almighty power of the God of Israel, who served his own purposes by the superstitions of the heathen. In reviewing our mercies, we should advert to former fears and distresses. When our mercies are personal, we should not by forgetfulness lose the comfort of them, or withhold from the Lord the glory due to his name. May the Lord teach us to rejoice, with that holy joy which anticipates and prepares for the blessedness of heaven. Every instance of Divine goodness to ourselves, is a new obligation laid on us to do good, to those especially who most need our bounty. Above all, redemption by Christ binds us to be merciful, 2Co 8:9.And the decree of Esther confirmed these matters of Purim,.... As a festival to be observed by the Jews in future generations:

and it was written in the book; either in this book of Esther; or in the public acts and chronicles of the kings of Persia; or in a book by itself, now lost, as Aben Ezra thinks, as many others are we read of in Scripture, as the books of the chronicles of the kings of Israel and Judah, &c.
