Dig a Pit and Fall In It - Esther 6-10

Esther 9:23-25 (ESV)
So the Jews accepted what they had started to do, and what Mordecai had written to them. For Haman the Agagite, the son of Hammedatha, the enemy of all the Jews, had plotted against the Jews to destroy them, and had cast Pur (that is, cast lots), to crush and to destroy them. But when it came before the king, he gave orders in writing that his evil plan that he had devised against the Jews should return on his own head, and that he and his sons should be hanged on the gallows.

The above passage is at the end of the book of Esther and it summarizes what happen in the previous chapters.   Haman was a bad man and a self-promoting official in King Ahasuerus’ kingdom.  He wanted to be second in command.  To achieve this rank he would need to please the king and to satisfy his own vengeance by taking out the Jew, Mordecai.   The tables are turned however, and it is Haman who, in his haste to be promoted and his vengeance to do harm, was hanged on the very gallows he intended to hang the subject of his vengeance: Mordecai.   So, the evil Haman meant for Mordecai become his dome and tomb.   Note how Solomon and the Psalms sum of the lessons of the book of Esther: 

Proverbs 26:27 (ESV)
Whoever digs a pit will fall into it,
and a stone will come back on him who starts it rolling.

Proverbs 28:10 (ESV)
Whoever misleads the upright into an evil way
will fall into his own pit,
but the blameless will have a goodly inheritance.

Psalms 7:14-16 (ESV)
Behold, the wicked man conceives evil
and is pregnant with mischief
and gives birth to lies.
He makes a pit, digging it out,
and falls into the hole that he has made.
His mischief returns upon his own head,
and on his own skull his violence descends.

The mischief of mankind that is imposed upon other men is noticed by God.   God is the God of justice and will vindicate those who walk with Him and for Him.   We can read the stories of Isaiah, Jeremiah and Daniel as prime examples of these very truths.   The world will come at those who believe in God and live for Christ.  But, the world will not prevail.   

1 John 4:4 (ESV)
Little children, you are from God and have overcome them, for he who is in you is greater than he who is in the world.
