John 18:20 (KJV)

And Simon Peter followed Jesus, and so did another disciple: that disciple was known unto the high priest, and went in with Jesus into the palace of the high priest.

But Peter stood at the door without. Then went out that other disciple, which was known unto the high priest, and spake unto her that kept the door, and brought in Peter.

Then saith the damsel that kept the door unto Peter, Art not thou also one of this man's disciples? He saith, I am not.

And the servants and officers stood there, who had made a fire of coals; for it was cold: and they warmed themselves: and Peter stood with them, and warmed himself.

The high priest then asked Jesus of his disciples, and of his doctrine.

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?

Now Annas had sent him bound unto Caiaphas the high priest.

And Simon Peter stood and warmed himself. They said therefore unto him, Art not thou also one of his disciples? He denied it, and said, I am not.
