And he shall pass over to his stronghold for fear, and his princes shall be afraid of the banner,
says the LORD, whose fire is in Zion, and his furnace in Jerusalem.
All Commentaries on Isaiah 31:9 Go To Isaiah 31
Gregory The Dialogist
AD 604
Of this love that is begun here to be perfected from the sight of the Lord in the eternal kingdom Isaiah rightly speaks, saying, “The Lord lives, whose fire is in Zion, and his furnace in Jerusalem.” It is, however, greater to be a furnace than a fire because a fire can also be small, but a larger flame is kindled in a furnace. Zion truly is said to be speculation but Jerusalem the vision of peace. Truly we sometimes catch a glimpse of our peace here in order there later to see it fully. Therefore through the Lord’s love the fire is in Zion and his furnace in Jerusalem because here we burn in some measure with the flames of his love when we glimpse him, but there we shall burn totally when we shall fully see him whom we love.
