Armageddon

Armageddon (Greek Αρμαγεδων; [armagedôn] also spelled Har-Magedon, or, in some modern English translations; the Mount of Megiddo), is the site of the final battle (or campaign) between God and Satan (whose name means 'adversary'), also known as the Devil. Satan will operate through the person known as the "The Beast" or the Antichrist, written about in the Book of Revelation in the New Testament. More generally, it can also refer to an apocalyptic catastrophe.

The word Armageddon in Scripture is known only from a single verse in the Greek New Testament, where it is said to be Hebrew, and is thought to represent the Hebrew words Har Megido (הר מגידו), meaning "Mountain of Megiddo". Megiddo was the location of many decisive battles in ancient times (see Battle of Megiddo).
