Armageddon: occurs only in Rev. 16:16 (R.V., "Har-Magedon"), as symbolically
designating the place where the "battle of that great day of God
Almighty" (ver. 14) shall be fought. The word properly means the
"mount of Megiddo." It is the scene of the final conflict
between Christ and Antichrist. The idea of such a scene was
suggested by the Old Testament great battle-field, the plain of
Esdraelon (q.v.).
