That you may say to the prisoners, Go forth; to them that are in darkness, Show yourselves. They shall feed in the ways, and their pastures shall be in all high places.
All Commentaries on Isaiah 49:9 Go To Isaiah 49
Ambrose of Milan
AD 397
[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.
