Acts 23:16-22

ISV(i) 16 But the son of Paul’s sister heard about the ambush, so he came and got into the barracks and told Paul. 17 Then Paul called one of the centurions and said, “Take this young man to the tribune, because he has something to tell him.”
18 So the centurion took him, brought him to the tribune, and said, “The prisoner Paul called me and asked me to bring this young man to you. He has something to tell you.”
19 The tribune took him by the hand, stepped aside to be alone with him, and asked, “What have you got to tell me?”
20 He answered, “The Jewish leaders have agreed to ask you to bring Paul down to the Council tomorrow as though they were going to examine his case more carefully. 21 Don’t believe them, because more than 40 of them are planning to ambush him. They’ve taken an oath not to eat or drink before they’ve killed him. They are ready now, just waiting for your consent.”
22 The tribune dismissed the young man and ordered him not to tell anyone that he had notified him.
