Luke 22:61

‘And the Lord turned, and looked on Peter. And Peter remembered the word of the Lord, how he had said to him, “Before the cock crow this day you will deny me three times.” '

And at that moment he became aware of Jesus, possibly at this point being led through the courtyard from one trial to another. And as his eyes lighted on Him, the Lord turned and looked at him. It was immediately clear to Peter that He knew exactly what had happened. And he remembered the words of Jesus and recognised the truth about what he had done. Within the aura of the Light of the world all his excuses collapsed. The truth was that instead of bearing witness to Jesus' innocence he had not only sat by and done nothing, he had denied him vehemently. Jesus' words had been fulfilled to the letter. He had denied his Lord three times.
