Isaiah 30:32

And in every place -Margin, ‘Every passing of the rod founded.’ Lowth renders it, ‘Whenever shall pass the rod of correction.’ The whole design of the passage is evidently to foretell the sudden destruction of the army of the Assyrians, and to show that this would be accomplished by the agency of God. The idea seems to be, that in all those places where the rod of the Assyrian would pass, that is, where he would cause devastation and desolation, there would be the sound of rejoicing with instruments of music when he should be overthrown.
