Midrash su Ester 6:7

"On that night the king's sleep fled" (Esth. 6:1). That night the throne of the King who is King of kings, the Holy One, blessed be He, became unsteady, because He saw that Israel was in great distress. The sleep of the king on earth fled, for he had seen in his dream Haman taking the sword to slay him; || and he became agitated and arose from his sleep, and he told the sons of Haman, the scribes, to read in the books so as to see what had happened to him. They opened the books, and found the incident which Mordecai had told, but they did not wish to read this, and they rolled up the scrolls. The king said to them: Read ye what is written before you. But they were unwilling to read, and the writing was read (of its own account) by itself, as it is said, "And they were read before the king" (ibid.). It is not written here, "They were reading," but "They were read." The king spake to his servants: Call ye Haman to me. They said to him: Behold, he is standing outside. The king said: The thing is true which I saw in my dream; he has come only in this hour to slay me. He said: Let him come in. He entered before the king. The king said to him: I wish to exalt and aggrandize a certain man; what shall be done to him? Haman said in his heart, for the seed of Esau speak in their hearts, but never reveal their secret with their mouths, as it is said, "And Haman said in his heart" (Esth. 6:6). Haman said in his heart: He does not desire to exalt any other man except me. I will speak words so that I shall be a king just as he is. He said to him: Let them bring the apparel || which the king wore on the day of the coronation, and (let them bring) the horse upon which the king rode on the coronation day, and the crown which was put upon the head of the king on the day of coronation. The king was exceedingly angry because of the crown. The king said: It does not suffice this villain, but he must even desire the crown which is upon my head. Haman saw that the king was angry because of the crown; he said: "And let the apparel and the horse be delivered to the hand of one of the king's most noble princes" (Esth. 6:9). (The king) said to him: Go, and do thus to Mordecai. As soon as Haman heard this he became greatly agitated, and he said to him: My lord, O king! There are very many named Mordecai. The king answered: "The Jew." (Haman) said to him: There are very many Jews. The king said to him: "He who sits at the king's gate" (Esth. 6:10).
