See the notes at Matthew 26:72-74.

And Simon Peter stood and warmed himself,.... This is repeated from John 18:18 to connect the history, and carry on the thread of the account of Peter's denial of Christ, which is interrupted by inserting the examination of Christ before the high priest, which was made at the same time. Peter stood among, and continued with the servants and officers of the high priest, warming himself by a fire they had made, it being a cold night; and this proved of bad consequence to him. The company and conversation of wicked men should be abstained from; no good is got thereby; continuance among such is very dangerous; men are too often more concerned for their bodies than their souls; Satan baits his temptations for the fleshly and sensitive part; and that which is thought to be for good, is the occasion of hurt.

They said therefore unto him; the servants and officers, among whom he stood warming himself, having observed what the maid had said to him:

art thou not also one of his disciples? suspecting that he was, though he had denied it, and therefore press him to give a direct answer: they might observe his countenance to fall, when the maid put the question to him; there might be something in his dress, and especially in his speech, which increased the suspicion:

but he denied it, and said, I am not; a second time. This denial of his being a disciple of Christ, as before, did not arise from a sense of his unworthiness to be one; nor from diffidence and distrust of a right to such a character; but from the fear of men; and being ashamed of Christ, he denies that which was his great mercy, privilege, and glory.

{9} And Simon Peter stood and warmed himself. They said therefore unto him, Art not thou also one of his disciples? He denied it, and said, I am not.

(9) After men have once fallen, they cannot only not lift themselves up by their own strength, but also they fall more and more into a worse condition, until they are raised up again by a new power from God.

18:15-27 For the trial of Jesus before Caiaphas and the denial of Peter, see notes on Mt 26:57-75. Compare Mr 14:53-72 Lu 22:54-71.

25. And Simon Peter was standing and warming himself. They said therefore . Art thou not also one of his disciples?-In Mt 26:71 the second charge was made by "another maid, when he was gone out into the porch," who "saw him, and said unto them that were there, This [fellow] was also with Jesus of Nazareth." So also Mr 14:69. But in Lu 22:58 it is said, "After a little while" (from the time of the first denial), "another [man] saw him, and said, Thou art also of them." Possibly it was thrown at him by more than one; but these circumstantial variations only confirm the truth of the narrative.

He denied it, and said, I am not-in Mt 26:72, "He denied with an oath, I do not know the man." This was THE SECOND DENIAL.

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.
