John 18:19-23

The high priest then asked Jesus of his disciples, and of his doctrine. Jesus answered him, I spake openly to the world; I ever taught in the synagogue, and in the temple, whither the Jews always resort; and in secret have I said nothing. Why askest thou me? ask them which heard me, what I have said unto them: behold, they know what I said. And when he had thus spoken, one of the officers which stood by struck Jesus with the palm of his hand, saying, Answerest thou the high priest so? Jesus answered him, If I have spoken evil, bear witness of the evil: but if well, why smitest thou me?
