Esther - God preserves the Jewish people through Esther's courage

In Esther Chapter 10, King Ahasuerus levies tribute throughout his empire, while Mordecai the Jew rises to second-in-command to the king. Mordecai becomes preeminent among his people, working for the welfare of the Jews and speaking peace to all his descendants.

And the king Ahasuerus laid a tribute upon the land, and upon the isles of the sea.

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?

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.
