Esther 10:2

And all the acts of his power, and of his might,.... As Xerxes was a very mighty and powerful prince:

and the declaration of the greatness of Mordecai, whereunto the king advanced him; the history of that, and which tended not a little to the greatness, dignity and prosperity of the king himself, and his whole kingdom:

are they not written in the book of the chronicles of the kings of Media and Persia? to which the reader is referred by the writer of this book, the which were in being in his times, but now lost: had they been preserved, they might have been of great use to lead into the history of the Medes and Persians, which for want of them is very dark and intricate; the writer of this book having nothing further to do with it, than as it related to the affairs of the Jews.
