Peter remembers Jesus' word and goes outside, weeping bitterly over it there alone that night.
It closes the denial with grief and remembrance of Jesus' word.
54Then they seized Jesus, led Him away, and took Him into the house of the high priest. And Peter followed at a distance. 55When those present had kindled a fire in the middle of the courtyard and sat down together, Peter sat down among them. 56A servant girl saw him seated in the firelight and looked intently at him. “This man also was with Him,” she said. 57But Peter denied it. “Woman, I do not know Him,” he said. 58A short time later, someone else saw him and said, “You also are one of them.” 59About an hour later, another man insisted, “Certainly this man was with Him, for he too is a Galilean.” 60“Man, I do not know what you are talking about,” Peter replied. 61And immediately, while he was still speaking, the rooster crowed. And the Lord turned and looked at Peter. 62Then Peter remembered the word that the Lord had spoken to him: “Before the rooster crows today, you will deny Me three times.” And he went outside and wept bitterly.
