Who is gathered around Jerusalem for the last great battle of Armageddon?
The surviving armies of the world—the residue of humanity still living—are gathered around Jerusalem for the last great battle of Armageddon. They come under military auspices, and God gathers them in the Middle East. These survivors have experienced the Tribulation's horrible events but remain unchanged.
Les explains that at the end of the Tribulation, after all the horrible events man has never experienced, those surviving in the armies of the world are all gathered around Jerusalem for that last great battle of Armageddon. Revelation 14 uses symbolic language of God gathering the residue of humanity still living, gathering them there in the Middle East under military auspices. The sickle and grape harvest imagery depict that gathering and judgment.
