He took Agag the king of the Amalekites alive, and utterly destroyed all the people with the edge of the sword.
"That Haman the ’Agagite’ (Esther 3:1; Esther 3:10; Esther 8:3; Esther 8:5; Esther 9:24) was an Amalekite is taken for granted by Josephus, who states that Haman’s determination to destroy all the Jews in Persia was in retaliation for Israel’s previous destruction of all his ancestors (Antiq. XI, 211 [vi.5])." [Note: Youngblood, p. 674.]
