'Prisoner of Christ Jesus' in the Bible

[This letter is from] Paul, a prisoner of Christ Jesus, and Timothy our brother, [and is being sent] to Philemon our dearly loved [brother] and fellow-worker,

yet out of [mutual] love, I appeal to you [to do what I ask]. For I Paul, am an old man, and now also a prisoner of Christ Jesus. [Note: Most calculations suggest that Paul was approximately 60 years old, which was considered a relatively advanced age in that day].
