Augustine of Hippo : Since by the command of the apostle we are not allowed to understand this as about the Jewish people but about Christians, what are we to understand in that which Isaiah says here, "you will quickly be built up by those from whom you fled," except the kings of the earth who formerly persecuted the church and later would help it as much as previously foretold. — LETTER TO THE CATHOLICS ON THE SECT OF THE DONATISTS 7:16 Theodoret of Cyrus : It is the king of Babylon who has destroyed Jerusalem and the king of the Persians who has ordained its reconstruction. But as these last were formerly subjects of the Assyrians, they also joined with them in taking the city. Thus, he can say that the same men both destroyed the city and reconstructed it. "And they that made you desolate shall depart from you." It is to levy the punishment for their faults that they have been delivered into the hands of their enemies. But it is the demons who are the cause of their faults, those they served in giving them the name of gods. He, therefore, predicts the end of the cult of idols and the deliverance from error. — COMMENTARY ON Isaiah 15:49.17
