Judges - Chapter 5

This chapter is a song by Deborah and Barak, praising God for the victory over Sisera.

The song makes it clear that the battle was decided in heaven and it gives the location as Megiddo:

“The kings came and fought, then the kings of Canaan fought in Taanach, by the waters of Megiddo; they took no spoils of silver. They fought from the heavens; the stars from their courses fought against Sisera."

In the book of Revelation - Chapter 16 - the Kings of the earth gather to battle against Jesus:

"For they are spirits of demons, performing signs, which go out to the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty. “Behold, I am coming as a thief. Blessed is he who watches, and keeps his garments, lest he walk naked and they see his shame.” And they gathered them together to the place called in Hebrew, Armageddon." - And the literal translation of the Hebrew for Armageddon is Mount Megiddo.
