From the presence of the terror of Jehovah, and from the glory of his majesty. What he adds about the terror of God must be understood to mean that terror which was thrown into them by the Chaldeans and Assyrians, whose hand he called a little before, and now also calls, the glory of God; for God employed their agency to chastise his people. Although they were wicked and treacherous, yet they promoted the glory of God; for even the devil himself contributes in some way to the glory of God, though contrary to his wish. Thus he speaks of the Assyrians and Chaldeans, because in the punishments which the Lord will inflict on the Jews by their agency we may behold his glory.
