Mark 14:66-68

66And as Peter was down in the courtyard, there cometh one of the maids of the high priest: 67And when she saw Peter warming himself, she looked upon him, and said, And thou also wast with Jesus of Nazareth. 68But he denied, saying, I know not, neither do I understand what thou sayest. And he went out into the porch; and the cock crowed.
