Boyd’s Bible Dictionary:

(famed). Prime minister of Ahasuerus, Esth.

Concise Bible Dictionary:

The chief minister of Ahasuerus in the time of Esther. He was called “the Agagite,” which associated him with the Amalekites, a people that had attacked Israel maliciously. Perpetual warfare had been pronounced against them by Jehovah and this accounts for Mordecai’s refusal to pay Haman reverence, which so wounded his pride and aroused his anger that he plotted to destroy not only Mordecai but all the Jews that were in the king’s dominions. His offer of the immense sum of 10,000 talents of silver ought to have shown the king that he had some sinister end in view. Lots were drawn to get a propitious day for their destruction. Not wishing however to wait for that distant day, he thought he would get rid of Mordecai at once by hanging him, and prepared a gallows for the purpose, intending in the morning to ask for his life. But God, who was watching over all, caused that the king on that very night should be reminded of Mordecai’s services, which resulted in Haman being compelled to take his intended victim through the city on the king’s horse, and proclaim him as the man whom the king delighted to honor. Then Esther pleaded for her life, and the salvation of her people, pointing out Haman as the one who had plotted their destruction; and he was hanged on the very gallows he had prepared for Mordecai (compare Prov. 26:27). The ten sons of Haman lost their lives also. Thus God watched over His people in their captivity and made the device of their enemy to fall upon his own head, as it will be with Satan (Esther 3-9).
