Rev 16:16 Gk. Harmageon, mount of Megiddo on the south side of the valley of Megiddo or Esdraelon southwest of Mount Carmel (2 Chron 35:22; Zech 12:11). Megiddo was the capital of a protion of Canaan that was given to Joshua (Josh 12:21; 17:11; 1:27). It is at the entrance to a pass across the Carmel mountain range, on the main highway between Asia and Africa and is the key position between Euphrates and the Nile. Thothmes III, the founder of the old Egyptian Empire, said, “Megiddo is worth a thousand cities”.
