Mark 14:66-70

And as Peter was beneath in the palace, there cometh one of the maids of the high priest:

And when she saw Peter warming himself, she looked upon him, and said, And thou also wast with Jesus of Nazareth.

But he denied, saying, I know not, neither understand I what thou sayest. And he went out into the porch; and the cock crew.

And a maid saw him again, and began to say to them that stood by, This is one of them.

And 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 agreeth thereto.
