Mark 14:66

And as Peter was beneath in the court, there cometh one of the maids of the high priest; and seeing Peter warming himself, she looked upon him and saith, Thou also wast with the Nazarene, even Jesus. But he denied, saying, I neither know, nor understand what thou sayest: and he went out into the porch; and the cock crew. And the maid saw him, and began again to say to them that stood by, This is one of them.

One may well sympathize with Peter. It was none of that maid's business whether Peter was or was not a disciple of Jesus; and Peter's purpose was clearly that of observing the proceedings unrecognized; but now this nosey maid was blabbering about his being a follower of Jesus. It is evident that Peter only wanted to get her to shut up. It was thus only a little deception that he proposed at first; but once a leak in the dyke appeared, the flood quickly overwhelmed him.

Peter tried to avoid further questioning by going out on the porch; but the maid saw him. As the devil's particular servant in that hour, she made it her business to run him down and pin the truth on him.

Hearing the cock crow while he was on the porch did not help Peter's nerves at all; and he returned to the unequal contest with the maid. She, on her part, sounded the alarm and appealed to everybody present. From John, it is plain that a relative of Malchus whose ear Peter had cut off was in the assemblage, and he took up the questioning also. This explains the fear and panic which came upon Peter and issued in his triple denial of the Lord.
