A servant girl noticed [Peter] in the firelight and began staring at him. Finally she said, “This man was one of Jesus’ followers!” But Peter denied it. “Woman,” he said, “I don’t even know him!” After a while someone else looked at him and said, “You must be one of them!” “No, man, I’m not!” Peter retorted. About an hour later someone else insisted, “This must be one of them, because he is a Galilean, too.” But Peter said, “Man, I don’t know what you are talking about.” And immediately, while he was still speaking, the rooster crowed. At that moment the Lord turned and looked at Peter. Suddenly, the Lord’s words flashed through Peter’s mind: “Before the rooster crows tomorrow morning, you will deny three times that you even know me.” And Peter left the courtyard, weeping bitterly.

After breakfast Jesus asked Simon Peter, “Simon son of John, do you love me more than these?” “Yes, Lord,” Peter replied, “you know I love you.” “Then feed my lambs,” Jesus told him. Jesus repeated the question: “Simon son of John, do you love me?” “Yes, Lord,” Peter said, “you know I love you.” “Then take care of my sheep,” Jesus said. A third time he asked him, “Simon son of John, do you love me?” Peter was hurt that Jesus asked the question a third time. He said, “Lord, you know everything. You know that I love you.” Jesus said, “Then feed my sheep.
