In Esther 7, the second banquet Queen Esther prepared for King Xerxes and Haman is happening. Once again, King Xerxes asks Queen Esther what her petition is. Once again, he offers up to half his kingdom. Queen Esther once again makes her request: "If I have found favor in your sight, O king, and if it pleases you, let my life be given me at my petition, and my people at my request. For we have been sold, my people and I, to be destroyed, to be killed, to be annihilated. Had we been sold as male and female slaves, I would have held my tongue, although the enemy could never compensate for the king's loss. Esther 7:3-4
The silence that followed must have been deafening. King Xerxes must have been in shock hearing this request. His mind must have been racing trying to process all of this. His queen had just told him someone was trying to kill her. Haman's face must have been pale because in that moment he realized he was about to be exposed.
King Xerxes then asked Queen Esther who would dare to do such a thing. Queen Esther then said, "The adversary and enemy is this wicked Haman!" Esther 7:6-7
It's not known if Esther pointed her finger at Haman as she made that statement or she was calm. What is known is that King Xerxes was ANGRY...and rightfully so. He was SO angry that he left the banquet and went into the palace garden. Sometimes it's a good idea to walk away when full-fledged angry because there's no telling what a person is capable of in that condition.
Meanwhile Haman is standing before Queen Esther pleading for his life. Up until that point, Haman wasn't anywhere close to being remorseful. He was too busy thinking about taking the lives of the Jews in the kingdom, especially Mordecai. It never occurred to him that the Queen he bowed before was a Jew herself. When he made the call to have the Jews executed, it never occurred to him that maybe things could go wrong.
But now that he's been exposed, he suddenly was sorry about what he had planned. There are a lot of people who apologize for their nasty actions and words not because of true remorse and repentance, but because they either got caught or they know they're at risk of losing everything. Haman was so desperate to save his own life that he literally fell upon Queen Esther pleading with her. There was NOTHING Haman could possibly do or say to justify his actions to a woman he determined should die.
Things got even worse when King Xerxes returned from the garden and saw him on Queen Esther. He was already extremely angry but seeing Haman on her took things to a whole other level. He says, "Will he also assault the queen while I am in the house?" Esther 7:7-8
Haman didn’t assault the queen, but at that point it didn't matter. Haman was going to be executed. It was then one of the eunuchs by the name of Harbonah told King Xerxes that Haman had gallows made for Mordecai. Remember that Mordecai had always been respectful to the king and had been the one who exposed the plot to have King Xerxes assassinated. The decision was made to hang Haman on those gallows, and he was. Haman was hung on the very same gallows he had set up for Mordecai. After that, the king's anger then subsided. Esther 7:9-10
A lot of people don't realize that when they set up situations for someone else's destruction, they're setting themselves up to have the same thing happen to them. Haman didn't know that God was watching him and was already making moves to make sure those evil plans didn't work.
Unfortunately, sometimes evil people do succeed in their horrible plans. Many people's lives have been destroyed because of the wicked traps and plans set up by evil people. But God is still good and powerful and one way or another, He is going to make those people pay. They may not be held accountable before man but they will see it again. A wise person once said, "As sure as the sun rises, they WILL see it again. It's not known if Haman had previously shed the blood of other Jews, but either way, it came back.
