Mark 14:68-71

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. 69And a maid saw him again, and began to say to them that stood by, This is one of them. 70And he denied it again. And a little after, they that stood by said again to Peter, Surely thou art one of them: for thou art a Galilaean, and thy speech showeth it . 71But he began to curse and to swear, saying, I know not this man of whom ye speak.
