26 Therefore they called these days “Purim, [1]” from the word “Pur.” Therefore because of all the words of this letter, and of that which they had seen concerning this matter, and that which had come to them, 27 the Jews established, and imposed on themselves, and on their descendants, and on all those who joined themselves to them, so that it should not fail, that they would keep these two days according to what was written, and according to its appointed time, every year; 28 and that these days should be remembered and kept throughout every generation, every family, every province, and every city; and that these days of Purim should not fail from among the Jews, nor the memory of them perish from their seed. 29 Then Esther the queen, the daughter of Abihail, and Mordecai the Jew, wrote with all authority to confirm this second letter of Purim. 30 He sent letters to all the Jews, to the hundred twenty-seven provinces of the kingdom of Ahasuerus, with words of peace and truth, 31 to confirm these days of Purim in their appointed times, as Mordecai the Jew and Esther the queen had decreed, and as they had imposed upon themselves and their descendants, in the matter of the fastings and their cry. 32 The commandment of Esther confirmed these matters of Purim; and it was written in the book.

(Read Esther 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, 2 Corinthians 8:9.
