Matthew 26:74

When he had gone out onto the porch, someone else saw him and said to those who were there, “This man also was with Jesus of Nazareth.”

Again he denied it with an oath, “I don’t know the man.”

After a little while those who stood by came and said to Peter, “Surely you are also one of them, for your speech makes you known.”

Peter remembered the word which Jesus had said to him, “Before the rooster crows, you will deny me three times.” Then he went out and wept bitterly.
