II. The ruin of Babylon, at last, is here likewise foretold, as it had been, long before, by Isaiah, v. 12-14. The destroyers must themselves be destroyed, and the rod thrown into the fire, when the correcting work is done with it. This shall be done when seventy years are accomplished; for the destruction of Babylon must make way for the deliverance of the captives. It is a great doubt when these seventy years commence; some date them from the captivity in the fourth year of Jehoiakim and first of Nebuchadrezzar, others from the captivity of Jehoiachin eight years after. I rather incline to the former, because then these nations began to serve the king of Babylon, and because usually God has taken the earliest time from which to reckon the accomplishment of a promise of mercy, as will appear in computing the 400 years' servitude in Egypt. And, if so, eighteen or nineteen years of the seventy had run out before Jerusalem and the temple were quite destroyed in the eleventh year of Zedekiah. However that be, when the time, the set time, to favour Zion, has come, the king of Babylon must be visited, and all the instances of his tyranny reckoned for; then that nation shall be punished for their iniquity, as the other nations have been punished for theirs. That land must then be a perpetual desolation, such as they had made other lands; for the Judge of all the earth will both do right and avenge wrong, as King of nations and King of saints. Let proud conquerors and oppressors be moderate in the use of their power and success, for it will come at last to their own turn to suffer; their day will come to fall. In this destruction of Babylon, which was to be brought about by the Medes and Persians, reference shall be had, 1. To what God had said: I will bring upon that land all my words; for all the wealth and honour of Babylon shall be sacrificed to the truth of the divine predictions, and all its power broken, rather than one iota or tittle of God's word shall fall to the ground. The same Jeremiah that prophesied the destruction of other nations by the Chaldeans foretold also the destruction of the Chaldeans themselves; and this must be brought upon them, v. 13. It is with reference to this very event that God says, I will confirm the word of my servant, and perform the counsel of my messengers, Isa. xliv. 26. 2. Two what they had done (v. 14): I will recompense them according to their deeds, by which they transgressed the law of God, even then when they were made to serve his purposes. They had made many nations to serve them, and trampled upon them with the greatest insolence imaginable; but not that the measure of their iniquity is full many nations and great kings, that are in alliance with and come in to the assistance of Cyrus king of Persia, shall serve themselves of them also, shall make themselves masters of their country, enrich themselves with their spoils, and make them the footstool by which to mount the throne of universal monarchy. They shall make use of them for servants and soldiers. He that leads into captivity shall go into captivity.
