John 18:19-21

19 Then the high priest questioned Jesus about his disciples and about his teaching.
20 Jesus answered, "I have spoken openly to the world; I have always taught in synagogues and in the temple, where all the Jews come together. I have said nothing in secret.
21 Why do you ask me? Ask those who heard what I said to them; they know what I said."
