'Prisoner of Jesus Christ' in the Bible

Paul, a prisoner of Jesus Christ, and Timothy our brother, unto Philemon our dearly beloved, and fellowlabourer,

to my sister Apphia, to my fellow soldier Archippus, and to the church which meets at Philemon's house. From Paul, a prisoner of Jesus Christ, and brother Timothy.

Yet for love's sake I rather beseech thee, being such an one as Paul the aged, and now also a prisoner of Jesus Christ.
