Acts 23:20-22

23:20 He replied, “The Jews have agreed to ask you to bring Paul down to the council tomorrow, as if they were going to inquire more thoroughly about him. 23:21 So do not let them persuade you to do this, because more than forty of them are lying in ambush for him. They have bound themselves with an oath not to eat or drink anything until they have killed him, and now they are ready, waiting for you to agree to their request.” 23:22 Then the commanding officer sent the young man away, directing him, “Tell no one that you have reported these things to me.”
