One of the servants of the high priest, being his kinsman whose ear Peter cut off, saith, Did not I see thee in the garden with him?

People's New Testament

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.

Jamieson-Fausset-Brown Bible Commentary

26. One of the servants of the high priest, being his kinsman, whose ear Peter cut off, saith, Did not I see thee in the garden with him-No doubt his relationship to Malchus drew attention to the man who smote him, and this enabled him to identify Peter. "Sad reprisals!" [Bengel]. The other Evangelists make his detection to turn upon his dialect. "After a while ['about the space of one hour after' (Lu 22:59)] came unto him they that stood by and said to Peter, Surely thou also art one of them, for thy speech betrayeth thee" (Mt 26:73). "Thou art a Galilean, and thy speech agreeth thereto" (Mr 14:70; and so Lu 22:59). The Galilean dialect had a more Syrian cast than that of Judea. If Peter had held his peace, this peculiarity had not been observed; but hoping, probably, to put them off the scent by joining in the fireside talk, he only thus revealed himself.

Matthew Henry's Concise Commentary

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.
