William Burkitt on Revelation 16:16

He, that is, Almighty God, by his permissive providence suffered the kings of the earth to hearken to antichrist's missionaries, who, like frogs, hop abroad even into kings' palaces, and persuade them to assemble and gather together, as Jabin and Sisera gathered together against Israel, to their own destruction: and whereas the place of their gathering together is called Armageddon, this is so named from the event of the battle; signifying such a place where the enemies of the church shall be destroyed.

Learn hence, That the event and success of that battle, which the adherents of antichrist shall fight for him, will be desperate destruction to themselves, joyful victories and triumphs to the churches of Christ.
