Then they gathered the kings together 
Revelation 16:14  They are demonic spirits that perform signs, and they go out to the kings of the whole world, to gather them for the battle on the great day of God Almighty.

to the place that in Hebrew 
Revelation 9:11  They had as king over them the angel of the Abyss, whose name in Hebrew is Abaddon and in Greek is Apollyon (that is, Destroyer.)

is called Armageddon 
Judges 5:19  "Kings came, they fought, the kings of Canaan fought. At Taanach, by the waters of Megiddo, they took no plunder of silver."
2 Kings 23:29-30  While Josiah was king, Pharaoh Necho king of Egypt went up to the Euphrates River to help the king of Assyria. King Josiah marched out to meet him in battle, but Necho faced him and killed him at Megiddo. Josiah's servants brought his body in a chariot from Megiddo to Jerusalem and buried him in his own tomb. And the people of the land took Jehoahaz son of Josiah and anointed him and made him king in place of his father.
2 Chronicles 35:20-24  After all this, when Josiah had set the temple in order, Necho king of Egypt went up to fight at Carchemish on the Euphrates, and Josiah marched out to meet him in battle. But Necho sent messengers to him saying, "What quarrel is there, king of Judah, between you and me? It is not you I am attacking at this time, but the house with which I am at war. God has told me to hurry; so stop opposing God, who is with me, or he will destroy you." Josiah, however, would not turn away from him, but disguised himself to engage him in battle. He would not listen to what Necho had said at God's command but went to fight him on the plain of Megiddo. Archers shot King Josiah, and he told his officers, "Take me away; I am badly wounded." So they took him out of his chariot, put him in his other chariot and brought him to Jerusalem, where he died. He was buried in the tombs of his ancestors, and all Judah and Jerusalem mourned for him.
Zechariah 12:11  On that day the weeping in Jerusalem will be as great as the weeping of Hadad Rimon in the plain of Megiddo.
