AGAG
Apparently, the generic title of the kings of Amalek, like Pharaoh was that of the Egyptians and probably Abimelech was that of the Philistines. Two are mentioned: Nm. 24:7 and 1 Sam. 15:9-33. Others believe that Numbers should read Gog, or also Og.
Haman (Est. 3:1) was probably descended from the Amalekite royal family.
