Footnote 7 – Why Megiddo?
John routinely borrows imagery from the Old Testament prophets, including Zechariah. For example, both Zechariah (6:1–8) and John (Revelation 6:1–8) have visions of four horses of different colors, and John’s account of the last battle in Jerusalem (Revelation 20:9) seems to have been influenced by Zechariah 14.
