Thematic Bible: This plan is thwarted by his nephew

But the son of Paul's sister heard of their ambush, and he came and entered the barracks and told Paul. Paul called one of the centurions to him and said, "Lead this young man to the commander, for he has something to report to him." So he took him and led him to the commander and said, "Paul the prisoner called me to him and asked me to lead this young man to you since he has something to tell you." read more.
The commander took him by the hand and stepping aside, began to inquire of him privately, "What is it that you have to report to me?" And he said, "The Jews have agreed to ask you to bring Paul down tomorrow to the Council, as though they were going to inquire somewhat more thoroughly about him. "So do not listen to them, for more than forty of them are lying in wait for him who have bound themselves under a curse not to eat or drink until they slay him; and now they are ready and waiting for the promise from you." So the commander let the young man go, instructing him, "Tell no one that you have notified me of these things."
