Philemon 1:10-14

that I appeal to you for my son Onesimus, who became my son while I was in chains. Formerly he was useless to you, but now he has become useful both to you and to me. I am sending him—who is my very heart—back to you. I would have liked to keep him with me so that he could take your place in helping me while I am in chains for the gospel. But I did not want to do anything without your consent, so that any favor you do would not seem forced but would be voluntary.
