Then Simon Peter. The other evangelists simply tell us that one of the number of the disciples performed the following act. The οὖν here is introduced between Simon and Peter, as if to imply that it was not merely Simon son of Jonas, but Simon the Rock, the man of mighty impulsive passion, ready, as he said a few hours since, to go with his Master to prison and to death.
The name and identification of Peter with the brave man who struck at least one blow for his Master, is a proof, not of John's animosity against Peter, or any desire to humble him, but rather to exalt him.
The extraordinary concomitance of this act with all the other delineations of Peter's character is another undesigned hint of the authenticity of the narrative. Simon Peter, then, having a sword. Here we see the unintentional agreement with the synoptic narrative (Luke 22:38).
Nothing would be less likely than that Peter should have a sword at his disposal; i.e. judging from the Johannine narrative. The Gospel of Luke explains it. Having a sword, he drew it, and smote the slave (not one of the ὑπηρέται, but the δοῦλος, body-servant) of the high priest, and eat off his right ear.
£ The slave, in receiving such a wound, must have been in fearful danger of his life. The reference to the right ear, mentioned also by Luke (Luke 22:50), is noteworthy. Now the name of the slave was Malchus.
Here the eye-witness, not the theologian, nor the dramatist, reveals his hand. Thoma sees, however, the fulfillment of prophetic outline, and a reference to the kings and chief captains, the Malchuses and chiliarchs, that are ultimately to flee before him.
The subsequently mentioned circumstance (verse 15) that the evangelist was "known to the high priest," explains this recovery of an otherwise valueless name. The instant when Peter cried, "Shall we smite with the sword?"
was most opportune. For the moment Peter felt that the whole band could be discomfited by a bold stroke. Christ with his word, the brave-hearted apostle with his weapon, could scatter all the foes of the Lord.
As on so many other occasions, Peter gives advice to the Master, only to find himself in grievous mistake.
