John Chrysostom : "Then Paul called one of the centurions unto him, and said, Bring this young man unto the tribune: For he hath a certain thing to tell him. So he took him, and brought him to the tribune, and said, Paul the prisoner called me unto him, and prayed me to bring this young man unto thee, who hath something to say unto thee. Then the tribune took him by the hand, and went with him aside privately, and asked him, What is that thou hast to tell me?" Again he is saved by man's forethought. And observe: Paul lets no man learn this, not even the centurion, that the matter might not become known. And the centurion having come, reported to the tribune. And it is well done of the tribune also, that he bids him keep it secret, that it might not become known. — Homily on Acts 49
