Matthew 26:71-75

And when he had gone out to the gateway, another girl saw him and said to those who were there, “This fellow also was with Jesus of Nazareth.” But again he denied with an oath, “I do not know the Man!” And a little later those who stood by came up and said to Peter, “Surely you also are one of them, for your speech betrays you.” Then he began to curse and swear, saying, “I do not know the Man!” Immediately a rooster crowed. And Peter remembered the word of Jesus who had said to him, “Before the rooster crows, you will deny Me three times.” So he went out and wept bitterly.
