9:27 The Jews ordained, and took upon them, and upon their seed, and upon all such as joined themselves unto them, so as it should not fail, that they would keep these two {q} days according to their writing, and according to their [appointed] time every year;
(q) Meaning, the fourteenth and fifteenth days of the month of Adar.
9:27 As joined - Gentile Proselytes; who were obliged to submit to other of the Jewish laws, and therefore to this also; the rather because they enjoyed the benefit of this day's deliverance; without which the Jewish nation and religion had been in a great measure, if not wholly, extinct. According - According to that writing which was drawn up by Mordecai, and afterwards confirmed by the consent of the Jews.
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.
