Mark 14:66-68

66While Peter was down below in the courtyard, one of the servant-girls of the high priest came,

67and when she saw Peter warming himself, she looked intently at him and said, “You were with Jesus the Nazarene, too.”

68But he denied it, saying, “I neither know nor understand what you are talking about.” Then he went out [of the courtyard] to the porch, [and a rooster crowed.]
