27 See, the name of the Lord is coming from far, burning with his wrath, with thick smoke going up: his lips are full of passion, and his tongue is like a burning fire: 28 And his breath is as an overflowing stream, coming up even to the neck, shaking the nations for their destruction, like the shaking of grain in a basket: and he will put a cord in the mouths of the people, turning them out of their way. 29 You will have a song, as in the night when a holy feast is kept; and you will be glad in heart, as when they go with music of the pipe to the mountain of the Lord, the Rock of Israel. 30 And the Lord will send out the sound of his great voice, and they will see his arm stretched out, with the heat of his wrath, and the flame of a burning fire; with a cloud-burst, and storm, and a rain of ice. 31 For through the voice of the Lord the Assyrian will be broken, and the Lord's rod will be lifted up against him. 32 And every blow of the rod of his punishment, which the Lord will send on him, will be with the sound of music: and with the waving of his sword the Lord will make war against him. 33 For a place of fire has long been ready; yes, it has been made ready for the king; he has made it deep and wide: it is massed with fire and much wood; the breath of the Lord, like a stream of fire, puts a light to it.

Commentary on Isaiah 30:27-33
(Read Isaiah 30:27-33)
God curbs and restrains from doing mischief. With a word he guides his people into the right way, but with a bridle he turns his enemies upon their own ruin. Here, in threatening the ruin of Sennacherib's army, the prophet points at the final and everlasting destruction of all impenitent sinners. Tophet was a valley near Jerusalem, where fires were continually burning to destroy things that were hurtful and offensive, and there the idolatrous Jews caused their children to pass through the fire to Moloch. This denotes the certainty of the destruction, as an awful emblem of the place of torment in the other world. No oppressor shall escape the Divine wrath. Let sinners then flee to Christ, seeking to be reconciled to Him, that they may be safe and happy, when destruction from the Almighty shall sweep away all the workers of iniquity.
