In chapter 6 the King realized that Mordecai had once done him a great favor that had not yet been rewarded, so he called Haman in and told him to go honor Mordecai for the unrewarded deed. Though Haman hated Mordecai, he had no choice but to do what the King commanded, but loathed every moment of it.
When Haman got home that night he whined to his family about how he had to honor Mordecai that day, the very Jew who had refused to honor Haman. I am sure he was expecting sympathy from his friends and his wife. But their answer to him was startling. That answer is recorded in Esther 6:13 "If Mordecai, before who you have begun to fall, is Jewish, you won't overcome him, because your downfall is certain."
I find it amazing that Haman's friends, who were no friends of the Jews, recognized that the Jews were special and that Haman would not be able to stand against them. Matthew Henry writes in his commentary that "they plainly confessed that the Jews, though scattered through the nations, were special objects of divine care. Miserable comforters are they all; they did not advise Haman to repent, but foretold his fate as unavoidable." Whether Haman's friends had access to the Old Testament or not, they clearly understood the teaching of Genesis 12:3, where God promised Abraham, "I will bless those who bless you, I will curse those who treat you with contempt, and all the peoples on earth will be blessed through you."
Almost since the beginning of Jewish history as a people, there have been those who sought to destroy them. Time and time again their people have been persecuted, often with great enthusiasm (see a list of Jewish persecutions here). But through God's supernatural protection, they have survived. This is something that we should take to heart in our modern world in which the Jews have somehow become the "bad" people of the Middle East. Though I do not always agree with the tactics that the nation of Israel uses against her enemies, I am not fool enough to put myself on the list of her enemies. For all their faults and misguided ideas, the Jews are still God's chosen people and if we stand against them, our fall is inevitable.
