Matthew 26:69-72

Now Peter was sitting without in the court: and a maid came unto him, saying, Thou also wast with Jesus the Galilæan. But he denied before them all, saying, I know not what thou sayest. And when he was gone out into the porch, another maid saw him, and saith unto them that were there, This man also was with Jesus of Nazareth. And again he denied with an oath, I know not the man.
