“For they are the spirits of devils, working miracles, which go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty. And he gathered them together into a place called in the Hebrew tongue Armageddon.” (Rev 16:14, 16)
No mention of battle at Armageddon
If a battle, it is symbolic; spiritual warfare.
Note change in person (they/he). Who gathered? God did? Why would he gather them to battle against him?
