(of Persian origin), magnificent, the name of the vizier (i.e., the prime minister) of the Persian king Ahasuerus (Esther 3:1, etc.). He is called an "Agagite," which seems to denote that he was descended from the royal family of the Amalekites, the bitterest enemies of the Jews, as Agag was one of the titles of the Amalekite kings. He or his parents were brought to Persia as captives taken in war. He was hanged on the gallows which he had erected for Mordecai the Jew (Esther 7:10). (See ESTHER.)
