Revelation 16:14. unto the kings: to marshal the forces of unrighteousness to resist the doom of God.

Revelation 16:16. The prophet resumes, and pictures the mustering of the forces on the final battle-field at Har-Magedon (the more correct way of spelling the familiar Armageddon). The name Har-Magedon means the mountains of Megiddo. We should naturally have looked for a word signifying the plain of Esdraelon on which Megiddo was situated, since that place was the scene of many battles in which the armies of Israel were concerned, and merited the description of G. A. Smith, the classic battleground of Scripture. There were mountains near at hand, however, and the writer may have been influenced by Ezekiel 38:8; Ezekiel 38:21; Ezekiel 39:2; Ezekiel 39:4, where the forces of Gog meet their overthrow upon the mountains of Israel (cf. Isaiah 14:25).
