Although Megiddo has been extensively chronicled in extra-biblical sources, it is only mentioned 12 times in the OT1 and once, indirectly, as Armageddon in the NT (Rv 16:16). Most Christians know the book of Revelation prophesies an end-times battle that will be fought at a place called Armageddon (Rv 16:16), and many know that Armageddon is, in fact, a corruption of the Greek word, Ἁρμαγεδών (Harmagedon) or “the hill of Megiddo.” A 35-acre (14 hectare) mound, 200 ft (60 m) high, in northwest Israel called Tell el-Mutesellim is believed to be the site of Megiddo.
