Power and might - In the later years of Xerxes his "power and might" were chiefly shown in the erection of magnificent buildings, more especially at Persepolis. He abstained from military expeditions.
Kings of Media and Persia - Media takes precedence of Persia because the kingdom of Media had preceded that of Persia, and in the "book of the Chronicles" its history came first.

The book of the chronicles of Media and Persia? - The Persians have ever been remarkable for keeping exact chronicles of all public events. Their Tareekhs, which are compositions of this kind, are still very numerous, and indeed very important.

the declaration of the greatness of Mordecai--The experience of this pious and excellent Jew verified the statement, "he that humbleth himself shall be exalted" [Matthew 23:12; Luke 14:11; Luke 18:14]. From sitting contentedly at the king's gate, he was raised to the dignity of highest subject, the powerful ruler of the kingdom. Acting uniformly on the great principles of truth and righteousness, his greatness rested on a firm foundation. His faith was openly avowed, and his influence as a professor of the true religion was of the greatest usefulness for promoting the welfare of the Jewish people, as well as for advancing the glory of God.

Chronicles, &c. - These are lost long since, and buried in oblivion, while the sacred writings remain throughout the world. When the kingdoms of men, monarchs and their monarchies are destroyed, and their memorial is perished with them, the kingdom of God among men, and the records of that kingdom, shall remain as the days of heaven.
