“Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me.”
John 21:22 — Greek Interlinear
Church Fathers on John 21:22

Peter seeing him says to Jesus, Lord, and what shall this man do?
I will that he tarry, i.e. I will not that he suffer martyrdom, but wait for the quiet dissolution of the flesh, when I shall come and receive him into eternal blessedness.
