John 18:21
'Why do you ask me? Ask those who heard what I said to them; they know what I said.' — Jesus deflects the interrogation back to the witnesses: the crowds who heard his public teaching can testify to its content. This reversal (turning examiner to witness) embodies Jesus' method throughout John: rather than defensive argumentation, he asserts truth's self-evident nature. The implicit challenge: my teaching cannot be honestly characterized by officials who will not consult unbiased witnesses.
