II. The persons brought together to lay Babylon waste are here called, 1. God's sanctified ones (v. 3), designed for this service and set apart to it by the purpose and providence of God, disengaged from other projects, that they might wholly apply themselves to this, such as were qualified for that to which they were called, for what work God employs men in he does in some measure fit them for. It intimates likewise that in God's intention, though not in theirs, it was a holy war; they designed only the enlargement of their own empire, but God designed the release of his people and a type of the destruction of the New-Testament Babylon. Cyrus, the person principally concerned, was justly called a sanctified one, for he was God's anointed (ch. xlv. 1) and a figure of him that was to come. It is a pity but all soldiers, especially those that fight the Lord's battles, should be in the strictest sense sanctified ones; and it is a wonder that those dare be profane ones who carry their lives in their hands. 2. They are called God's mighty ones, because they had their might from God and were now to use it for him. It is said of Cyrus that in this expedition God held his right hand, ch. xlv. 1. God's sanctified ones are his mighty ones. Those whom God calls he qualifies; and those whom he makes holy he makes strong in spirit. 3. They are said to rejoice in his highness, that is, to serve his glory and the purposes of it with great alacrity. Though Cyrus did not know God, nor actually design his honour in what he did, yet God used him as his servant (ch. xlv. 4, I have surnamed thee as my servant, though thou hast not known me), and he rejoiced in those successes by which God exalted his own name. 4. They are very numerous, a multitude, a great people, kingdoms of nations (v. 4), not rude and barbarous, but modelled and regular troops, such as are furnished out by well-ordered kingdoms. The great God has hosts at his command. 5. They are far-fetched: They come from a far country, from the end of heaven. The vast country of Assyria lay between Babylon and Persia. God can make those a scourge and ruin to his enemies that lie most remote from them and therefore are least dreaded.
