Peter took him ( προσλαβόμενος). Either taking him aside, or taking him by the hand or dress—a reverent familiarity permitted by the Lord to his loving apostle. And now this same Peter, who had just before made his noble confession, and had been rewarded with unique commendation, unable to shake off the prejudices of his age and his education, began to rebuke ( ἐπιτιμᾶν) his Master.
He presumed to chide Jesus for speaking of suffering and death. He, the Son of God most High, what had he to do with such things? How could he name them in connection with himself? Peter, while accepting the idea of Messiah as Divine and triumphant, could not receive the notion of his death and Passion.
That the same person should be so humiliated and yet so glorious, was beyond his conception. He was as much in the dark as his fellow apostles; of that which was not specially revealed to him he knew nothing.
It was the carnal mind that here influenced him, not the spiritually enlightened soul. By writing "began," the historian intimates that he had not time to say much before the Lord mercifully interposed and cut him short.
Be it far from thee; ἵλεώς σοι: Vulgate, absit a te. The Greek phrase is elliptical, εἴη ὁθεός being understood; "God be merciful to thee," equivalent to "God forbid." The complete expression occurs in the Septuagint of 1 Chronicles 11:19.
It is used in deprecation of a disastrous event. This shall not be unto thee; οὐ μὴ ἔσται σοι τοῦτο. This is a very strong assertion, not a prayer or wish, as some would make it; the use of language is quite against that, as the phrase is predictive, never prohibitory, in his mistaken zeal and his ignorant affection, Peter would be wiser than his Lord.
The cross and Passion shall never be thy lot; Messiah cannot suffer, the Son of God cannot die. Such merely human asseveration, even prompted by undoubted love, had to be checked and rebuked.
