The Prophet proceeds here to the Assyrians, whom we know to have been special enemies to the Church of God. For the Moabites and the Ammonites were fans only, as we have elsewhere seen, as they could not do much harm by their own strength. Hence they stirred up the Assyrians, they stirred up the Ethiopians and remote nations. The meaning, then, is, that no one of all the enemies of the Church would be left unpunished by God, as every one would receive a reward for his cruelty. He speaks now of God in the third person; but in the last verse God himself said, that the Ethiopians would be slain by his sword. The Prophet adds here, He will extend his hand to the north; that is, God will not complete his judgments on the Ethiopians; but he will go farther, even to Nineveh and to all the Assyrians.
