Isaiah 31:9

And he shall pass over to his stronghold for fear, that is, the king of Assyria, hitherto the strong refuge of his people, would flee in terror, and his princes shall be afraid of the ensign, scattered in wild confusion before the onslaught of Jehovah, saith the Lord, whose fire is in Zion and His furnace in Jerusalem, the light of His divine presence shining forth from His holy congregation. With God in her midst, with the illuminating light of His Word and with the destroying power of His wrath over against His enemies, the Church of God of all times is secure.
