Charles Ellicott Commentary Acts 23:18

"So he took him, and brought him to the chief captain, and saith, Paul the prisoner called me unto him, and asked me to bring this young man unto thee, who hath something to say to thee." — Acts 23:18 (ASV)

Paul the prisoner . . .—We may well believe that at the time he little thought how long that name would be applied to him, first by others and then by himself, until it became a title of honor in which he seemed to take pride almost more than in the title of Apostle. (Ephesians 4:1; Philemon 1:1; Philemon 1:9.)
