John 21:22

“Jesus saith unto him, etc.] Christ vouchsafes an answer to Peter, but not a very clear one, nor such an one as he wished for, and not without a rebuke to him: if I will that he tarry till I come, what is that to thee? meaning, that if it was his pleasure that he should live, not till his second coming to judge the quick and dead at the last day, but till he should come in his power and take vengeance on the Jewish nation, in the destruction of their city and temple by the Romans, and in dispersing them through the nations of the world; till which time John did live, and many years after; and was the only one of the disciples that lived till that time, and who did not die a violent death;…”

“Jesus saith to him, If I will that he tarry fill I come, what is that to thee? follow thou me--From the fact that John alone of the Twelve survived the destruction of Jerusalem, and so witnessed the commencement of that series of events which belongs to "the last days," many good interpreters think that this is a virtual prediction of fact, and not a mere supposition. But this is very doubtful, and it seems more natural to consider our Lord as intending to give no positive indication of John's fate at all, but to signify that this was a matter which belonged to the Master of both, who would disclose or conceal it as He thought proper, and that Peter's part was to mind his own affairs.…”

“That he tarry - That he live. The same word is used to express life in Phi 1:24-25; 1 Corinthians 15:6. Till I come - Some have supposed this to refer to the destruction of Jerusalem; others to the day of judgment; others to signify that he would not die a violent death; but the plain meaning is, “If I will that he should not die at all, it is nothing to thee.” In this way the apostles evidently understood it, and hence raised a report that he would not die. It is remarkable that John was the last of the apostles; that he lived to nearly the close of the first century, and then died a peaceful death at Ephesus, being the only one, as is supposed, of the apostles who did not suffer martyrdom.…”

“If I will that he tarry - Without dying, till I come - To judgment. Certainly he did tarry, till Christ came to destroy Jerusalem. And who can tell, when or how he died? What is that to thee? - Who art to follow me long before. John 21:23”
