Either the devil brought them together, or God by his providence ordered that they should be gathered together, into the place where God designed to destroy them and their armies, for so the word Armageddon signifieth, say some; but others make it to signify the mountain of the gospel, or the mountain of apples, or fruits; but the first etymology in this place seems best. The word doth not signify any particular place; but here is an allusion, as some think, to that Megiddo, mentioned Judges 5:19, where Barak overcame Sisera with his great army, and where Josiah was slain, 2 Kings 23:30. Of the issue of this last battle with the enemies of the church of Christ we shall read more, Revelation 19:1-21.
