John Chrysostom : Again human forethought is saved. See, Paul allowed nobody to learn of this, not even the centurion, so that the matter might not be divulged. Instead, the centurion took him and brought him to the tribune. The tribune rightly ordered that he be hidden, so that the matter would remain secret. Then he told the centurions what had to be done. — CATENA ON THE ACTS OF THE APOSTLES 23.17-21 John Chrysostom : "And when Paul's sister's son heard of their lying in wait, he went and entered into the castle, and told Paul." This was of God's providence, their not perceiving that it would be heard. What then did Paul? he was not alarmed, but perceived that this was God's doing: and casting all upon Him, so he acquits himself from further concern about it. — Homily on Acts 49 John Chrysostom : "Paul's sister's son heard of it." This was of God's providence, their not perceiving that it would be heard. What then did Paul? he was not alarmed, but perceived that this was God's doing: and casting all upon Him, so he acquits himself from further concern about it: "having called one of the centurions," etc. He told of the plot, he was believed; he is saved. — Homily on Acts 49
