2. It was that the Israel of God might be released, v. 4. Cyrus knew not God as the God of Israel. Having been trained up in the worship of idols, the true God was to him an unknown God. But, though he knew not God, God not only knew him when he came into being, but foreknew him, and bespoke him for his shepherd. He called him by his name, Cyrus, nay, which was yet great honour, he surnamed him and called him his anointed. And why did God do all this for Cyrus? Not for his own sake, be it known to him; whether he was a man of virtue or no is questioned. Xenophon indeed, when he would describe the heroic virtues of an excellent prince, made use of Cyrus's name, and many of the particulars of his story, in his Cyropædia; but other historians represent him as haughty, cruel, and bloodthirsty. The reason why God preferred him was for Jacob his servant's sake. Note, (1.) In all the revolutions of states and kingdoms, the sudden falls of the great and strong, and the surprising advancements of the weak and obscure, God is designing the good of his church. (2.) It is therefore the wisdom of those to whom God has given wealth and power to use them for his glory, by showing kindness to his people. Cyrus is preferred that Israel may be released. He shall have a kingdom, only that God's people may have their liberty; for their kingdom is not of this world, it is yet to come. In all this Cyrus was a type of Christ, who was made victorious over principalities and powers, and entrusted with unsearchable riches, for the use and benefit of God's servants, his elect. When he ascended on high he led captivity captive, took those captives that had taken others captives, and opened the prison to those that were bound.
