15 Now Simon Peter followed Jesus, and the other disciple. But that disciple was known to the high priest, and went in with Jesus into the palace of the high priest; 16 but Peter stood at the door without. The other disciple therefore, who was known to the high priest, went out and spoke to the porteress and brought in Peter. 17 The maid therefore, who was porteress, says to Peter, Art thou also of the disciples of this man? He says, I am not. 18 But the bondmen and officers, having made a fire of coals (for it was cold), stood and warmed themselves; and Peter was standing with them and warming himself.

Commentary on John 18:13-27
(Read John 18:13-27)
Simon Peter denied his Master. The particulars have been noticed in the remarks on the other Gospels. The beginning of sin is as the letting forth of water. The sin of lying is a fruitful sin; one lie needs another to support it, and that another. If a call to expose ourselves to danger be clear, we may hope God will enable us to honour him; if it be not, we may fear that God will leave us to shame ourselves. They said nothing concerning the miracles of Jesus, by which he had done so much good, and which proved his doctrine. Thus the enemies of Christ, whilst they quarrel with his truth, wilfully shut their eyes against it. He appeals to those who heard him. The doctrine of Christ may safely appeal to all that know it, and those who judge in truth bear witness to it. Our resentment of injuries must never be passionate. He reasoned with the man that did him the injury, and so may we.
