When Paul's sister's son heard, &c. How privately soever this business was contrived, the providence of God so ordered it, that, for the deliverance of his faithful servant from this inhuman and bloody conspiracy, it came to the ears of Paul's nephew; who went and entered into the castle Where, as has been before observed, Paul now lay confined; and told him the whole matter. Then Paul called one of the centurions Who commanded part of the cohort under the tribune; and said, Bring this young man unto the chief captain Thus we see that Paul, though he had an express promise of it from Christ, did not neglect any proper means of safety. The chief captain took him by the hand In a mild, condescending way; and went aside privately Where none could overhear them speaking; and asked what he had to tell him Lysias seems to have conducted this whole affair with great integrity, humanity, and prudence. So the chief captain Having received the information which the young man had to give; let him depart, charging him to tell no man what things they were that he had communicated.
Acts 23:16-22
16 And when Paul's sister's son heard of their lying in wait, he went and entered into the castle, and told Paul.
17 Then Paul called one of the centurions unto him, and said, Bring this young man unto the chief captain: for he hath a certain thing to tell him.
18 So he took him, and brought him to the chief captain, 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.
19 Then the chief captain took him by the hand, and went with him aside privately, and asked him, What is that thou hast to tell me?
20 And he said, The Jews have agreed to desire thee that thou wouldest bring down Paul to morrow into the council, as though they would enquire somewhat of him more perfectly.
21 But do not thou yield unto them: for there lie in wait for him of them more than forty men, which have bound themselves with an oath, that they will neither eat nor drink till they have killed him: and now are they ready, looking for a promise from thee.
22 So the chief captain then let the young man depart, and charged him, See thou tell no man that thou hast shewed these things to me.
