Esther 10:1 And the king Ahasuerus laid a tribute upon the land, and upon the isles of the sea.

Esther 10:2 And all the acts of his power and of his might, and the declaration of the greatness of Mordecai, whereunto the king advanced him, are they not written in the book of the chronicles of the kings of Media and Persia?

Esther 10:3 For Mordecai the Jew was next unto king Ahasuerus, and great among the Jews, and accepted of the multitude of his brethren, seeking the wealth of his people, and speaking peace to all his seed.

 

The book closes with a statement that King Ahasuerus commanded a tribute throughout the whole of his kingdom. 

 

All the acts of his power and might and an account of the greatness of Mordecai are written in the chronicles of the kings of Media and Persia.  Mordecai the Jew was second in command to king Ahasuerus, a very great man among the Jews.  He was greatly honored among his people because he worked for their betterment and for the betterment of their descendants.

 

Gill offers a bit of information about the fate of Mordecai and Esther:  No mention is made in this history of the death and burial either of Mordecai or Esther; but the author of Cippi Hebraici says, that Mordecai was buried in the city of Shushan, and that all the Jews in those parts assemble at his grave on the day of Purim, and sing songs, playing on tabrets and pipes, rejoicing that there was a miracle wrought; and the same writer says, they do the like at that time at the grave of Esther, half a mile from Tzephat, read this book that bears her name, eat, drink, and rejoice. Benjamin of Tudela says, they were both buried before a synagogue, at a place called Hamdan.

 

I found a bit more at http://www.encyclopedia.com/philosophy-and-religion/bible/old-testament/esther:   Esther reigned as the queen of Persia for a period of about 13 years. With King Ahasuerus, she had one son, named Darius II, who would later rebuild the holy Temple in Jersusalem. It is believed that her life extended into the reign of her stepson, Artaxerxes. Although the date of her death is not known, Jewish tradition indicates that Queen Esther's tomb is in Hamadan, also known as Ecbatana, located in what is now western Iran.

 

I found this quote from Spurgeon summarizing the book of Esther at http://www.preceptaustin.org/esther_8-10_commentaryThere it is; man is a free agent in what he does, responsible for his actions, and verily guilty when he does wrong, and he will be justly punished too, and if he be lost the blame will rest with himself alone: but yet there is One who ruleth over all, who, without complicity in their sin, makes even the actions of wicked men to subserve his holy and righteous purposes. Believe these two truths and you will see them in practical agreement in daily life, though you will not be able to devise a theory for harmonizing them on paper.
