Boyd’s Bible Dictionary:
(hill of Megiddo). A typical battlefield between the hosts of good and evil (Rev. 16:16).
Concise Bible Dictionary:
The Hebrew name of the place where the kings of the earth and of the whole world will be gathered together to make war against the Lord Jesus in the great day of Almighty God (Rev. 16:16). There seems to be an allusion to the great battle field of Palestine in the Esdraelon, and to the Megiddo mentioned in Judges 5:19, 1 Kings 4:12 and 2 Kings 23:29-30. The word itself is translated “the mountain of slaughter,” and may be used symbolically for the destruction that will surely fall upon the enemies of the Lord Jesus.
