One of them which were with Jesus - John informs us that this was Peter.

The other evangelists concealed the name, probably because they wrote while Peter was living, and it might have endangered Peter to have it known.

And drew his sword - The apostles were not commonly armed. On this occasion they had provided "two swords," Luke 22:38. In seasons of danger, when traveling, they were under a necessity of providing means of defending themselves against the robbers that infested the country. This will account for their having any swords in their possession. See the notes at Luke 10:30. Josephus informs us that the people were accustomed to carry swords under their garments as they went up to Jerusalem.

A servant of the high-priest - His name, John informs us, was "Malchus." Luke adds that Jesus touched the ear and healed it, thus showing his benevolence to his foes when they sought his life, and giving them proof that they were attacking him that was sent from heaven.

One of them which were with Jesus - This was Peter - struck a servant of the high priest's, the servant's name was Malchus, John 18:10, and smote off his ear. In Luke 22:51, it is said, Jesus touched and healed it. Here was another miracle, and striking proof of the Divinity of Christ. Peter did not cut the ear, merely, he cut it Off, αφειλεν. Now to heal it, Jesus must either take up the ear and put it on again, or else create a new one - either of these was a miracle, which nothing less than unlimited power could produce. See the note on John 18:10.

And behold one of them which were with Jesus,.... Either one of the three that Jesus took with him whilst he was in his agony, leaving the other eight at some distance; or of the eleven, who might now be all with him: however, it is certain, Peter is the person meant; for though he is not named here, nor by Mark, nor Luke, he is by John, John 18:10; whose Gospel being wrote last, and many years after the rest, there was no danger like to accrue, by telling who it was that did the following action: he being now thoroughly awaked with the rest, by what Christ had said to him; and more so by the surprise of the multitude of armed men about him; and remembering his solemn protestations of abiding by his master; and seeing him just now ready to be seized, and carried away; without knowing his master's mind, or waiting his answer to the question the other disciples put,

stretched out his hand, and drew his sword, and struck a servant of the high priest's, and smote off his ear. It seems he had a sword by his side, upon what account is not certain; this he drew, and struck at a servant of the high priest's, who might show great malignity against Christ, and was foremost, and most busy in apprehending him. The blow was levelled at his head, and with an intention, no doubt, to have, cleaved him down, but sloping on one side took off his ear. The servant's name was Malchus, as John says; and it was his right ear that was cut off, as both he and Luke relate, John 18:10.

The servant (τὸν δοῦλον)

The article marks the special servant; the body-servant.

Ear (ὠτίον)

A diminutive in form but not in sense; according to a Greek popular usage which expressed parts of the body by diminutives; as ῥίνια, the nostrils; ὀμμάτιον, the eye; σαρκίον, the body. Peter aimed his blow at the servant's head, but missed.

And, behold, one of them which were with Jesus stretched out his hand, and drew his sword, and struck a servant of the high priest's, and smote off his ear.

26:51 One... drew his sword. Peter (Joh 18:26).

Struck a servant of the high priest's. As we learn from John, his name was Malchus (Joh 18:10). The Lord healed his wound (Lu 22:51). Peter asked, Shall we smite with the sword ? and without waiting for an answer, struck the blow (Lu 22:49,50).

26:51 And one of them striking the servant of the high priest - Probably the person that seized Jesus first; Cut off his ear - Aiming, it seems, to cleave his head, but that by a secret providence interposing, he declined the blow. Mark 14:47; Luke 22:49; John 18:10.

26:47-56 No enemies are so much to be abhorred as those professed disciples that betray Christ with a kiss. God has no need of our services, much less of our sins, to bring about his purposes. Though Christ was crucified through weakness, it was voluntary weakness; he submitted to death. If he had not been willing to suffer, they could not conquer him. It was a great sin for those who had left all to follow Jesus; now to leave him for they knew not what. What folly, for fear of death to flee from Him, whom they knew and acknowledged to be the Fountain of life!
