Mark 14:66-69

66And as Peter was beneath in the court, there cometh one of the maids of the high priest;

67and seeing Peter warming himself, she looked upon him, and saith, Thou also wast with the Nazarene, even Jesus.

68But he denied, saying, I neither know, nor understand what thou sayest: and he went out into the porch; and the cock crew.

69And the maid saw him, and began again to say to them that stood by, This is one of them.
