agag

Agag was the king of the Amalekites, mentioned by Balaam in Numbers xxiv.7 in a way that gives probability to the conjecture that the name was a standing title of the kings of Amalek. The name or title may mean "flame" in ancient West Semitic.Another Amalekite ruler named Agag was taken alive by King Saul after destroying the Amalekites (I Sam. xv.). His life was spared by Saul and the Israelites took the best of the sheep, cattle, fat calves and lambs from the Amalekites. It is possible that Agag was a title similar to the Egyptians' "Pharoah", the Roman "Caesers", or today's 'Mr. President'.

(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 1Sam 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; 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. (B.C. about 1070.) 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.
