I prefer some variant of “get thee behind me Satan.”
Ah, but there's a profound difference here — in Peter's case he's saying This shall never happen to you!
(concerning the Crucifixion, the whole reason for Jesus's presence on Earth) — in this case it's more akin to Caiaphas in John 11:
But one of them, Caiaphas, who was high priest that year, said to them, “You know nothing at all! You do not understand that it is better for you to have one man die for the people than to have the whole nation destroyed.” He did not say this on his own, but being high priest that year he prophesied that Jesus was about to die for the nation, and not for the nation only, but to gather into one the dispersed children of God. So from that day on they planned to put him to death.
