Matthew 16:21-23
From that time on, Jesus began to show his disciples that he must go to Jerusalem and undergo great suffering at the hands of the elders and chief priests and scribes, and be killed, and on the third day be raised. And Peter took him aside and began to rebuke him, saying, “God forbid it, Lord! This must never happen to you.” But he turned and said to Peter, “Get behind me, Satan! You are a stumbling block to me; for you are setting your mind not on divine things but on human things.”
