VI. God appearing, at length, in his glory against his proud invader, v. 10-12. When things are brought thus to the last extremity, 1. God will magnify himself. He had seemed to sit by as an unconcerned spectator: "But now will I arise, saith the Lord; now will I appear and act, and therein I will be not only evidenced, but exalted." He will not only demonstrate that there is a God that judges in the earth, but that he is God over all, and higher than the highest. "Now will I lift up myself, will prepare for action, will act vigorously, and will be glorified in it." God's time to appear for his people is when their affairs are reduced to the lowest ebb, when their strength is gone and there is none shut up nor left, Deut. xxxii. 36. When all other helpers fail, then is God's time to help. 2. He will bring down the Assyrian: "You, O Assyrians! are big with hopes that you shall have all the wealth of Jerusalem for your own, and are in pain till it be so; but all your hopes shall come to nothing: You shall conceive chaff, and bring forth stubble, which is not only worthless and good for nothing, but combustible and proper fuel for the fire, which it cannot escape, when your own breath as fire shall devour you, that is, the breath of God's wrath, provoked against you by the breath of your sins—your malignant breath, the threatenings and slaughter you breathe out against the people of God, this shall devour you, and your blasphemous breath against God and his name." God would make their own tongues to fall upon them, and their own breath to blow the fire that should consume them; and then no wonder that the people are as the burnings of lime in a lime-kiln, all on fire together, and as thorns cut up, which are dried and withered, and therefore easily take fire and are soon burnt up. Such was the destruction of the Assyrian army; it was like the burning up of thorns, which can well be spared, or the burning of lime, which makes it good for something. The burning of that army enlightened the world with the knowledge of God's power and made his name shine brightly.
