(flame), possibly the title of the kings of Amalek, like Pharaoh of Egypt. One king of this name is mentioned in (Numbers 24:7) and another in 1 Samuel 15:8-9, 20, 32. The latter was the king of the Amalekites, whom Saul spared contrary to Jehovah’s well-known will (Exodus 17:14; Deuteronomy 25:17). For this act of disobedience Samuel was commissioned to declare to Saul his rejection, and he himself sent for Agag and cut him in pieces (see Samuel). Haman is called the Agagite in Esther 3:1, 10; 8:3, 5. The Jews consider him a descendant of Agag the Amalekite.
