Verse 20. - Mordecai wrote these things. Mordecai seems, in the first instance, to have written to the provincial Jews, suggesting to them the future observance of two days of Purim instead of one, and explaining the grounds of his proposition, but without venturing to issue any order. When he found his proposition well received (vers. 23, 27) he sent out a second letter, "with all authority" (ver. 29), enjoining the observance.

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 Mordecai wrote these things,.... The transactions of those two days, and the causes of them, as well as the following letter; some conclude from hence that he was the penman of the book; and so he might be, but it does not necessarily follow from hence:

and sent letters unto all the Jews that were in all the provinces of the King Ahasuerus, both nigh and far; such as were near the city Shushan, and those that were at the greatest distance from it; these were more especially the things he wrote.
