Megiddo, Megiddon
Archimandrite Nikifor’s Biblical Encyclopedia
(Josh 12:21) (city of good fortune) — a city of the half-tribe of Manasseh, on the border of the tribe of Issachar, not far from the brook Kishon, whose waters are accordingly called the waters of Megiddo (Judg 5:19), and the plain of Israel is called the plain of Megiddo (2 Chr 35:22). The inhabitants of Megiddo were not originally driven out by the tribe of Manasseh, but when Israel grew strong they became its tributaries. Solomon fortified the city of Megiddo and made it the residence of one of his twelve officers over provisions for his household (1 Kings 4:12).
Here Ahaziah, king of Judah, died of a wound received in battle with Jehu; here too was slain, during the battle with Pharaoh Necho, king of Egypt, the pious king of Judah, Josiah (2 Kings 23:29), a defeat which the prophet Zechariah also refers to (12:11). The height of the city is called in Revelation Armageddon (Rev 16:16). The Romans called this city Legio, and at the present day it is called El-Lejjun, situated on high ground near the brook Kishon.
