Ambrose of Milan : [When] we have changed our creditor, we have not entirely escaped, or, rather, we have escaped, but the debt remains, while the interest is canceled, the Lord Jesus saying, "To them that are bound, come forth. And to them that are in prison, go forth," for your sins have been forgiven. He has forgiven all, and there is no one whom he has not set free. — LETTER 62 Theodoret of Cyrus : To apply these words to Zerubabbel is absolute nonsense. For Zerubbabel led the Jews out of Babylon, but he did not deliver the nations from error or present the new covenant to the nations. Isaiah says these things about the Lord Christ; it is Christ who has filled the wilderness of the world with divine shoots. He has restored the ruined earth, set those trapped in sins free from chains and illuminated those sitting in darkness with the light of the knowledge of God. — COMMENTARY ON Isaiah 15:49.8-9
