Eusebius of Caesarea : It is possible to contemplate the fulfillment of the divine word when one sees, in consequence of the conversion of the nations, such souls dedicating themselves to the message of godliness and being diligently busy in the ministry of the altar of God. It is then especially on account of the conversion of such souls and their salvation that the church of God receives glory. — COMMENTARY ON Isaiah 2:50 Procopius of Gaza : He calls the ships "from Tharsis," those that come from Tharsis in India, which is situated in the far east and puts us in mind of Jonah. These will come to Jerusalem not for its sake but for God, who wished to ratify the promise made to the ancestors through his great mercy. And next, "And strangers will build you walls." This can now be seen, for the Gentiles lead the churches and fence them round with their teachings, so that there is no place for a contrary word of counsel. "And their kings will minister to you." For even today the leaders of the Roman administration and the fear of kings restrain those plotting against the churches. Indeed, "minister" means their subordination. For they listen to the church's holy oracles and value the gospel message with all consideration. — COMMENTARY ON Isaiah 60:1.22 Theodore of Heraclea : We need to observe how the Lord, out of his benevolence, foretells all things before they happen. When he threatens doom, this is so that his servants, afraid of what might happen, will turn and repent and manage to deflect the terrible trials. Again, blessings are promised, and these promises strengthen the souls of those who act justly, providing them with hope before God. But there is never any necessity on God to carry out these things. For when people repent there is no need for anger, or, when they do not persevere in doing good, he will not [necessarily] bring to an end the promised blessings either, we ourselves being the ones who provide the reasons for God to execute the promised harm.And these events can be discovered if one looks, for instance, at when Cyrus and then Darius rebuilt Jerusalem. Also, no less a person than Alexander was impressed by the sacred vestment and turned anger into worship. — FRAGMENTS ON ISAIAH
