Matthew 16:13-18, 21-23

Now when Jesus came into the region of Caesarea Philippi, He was asking His disciples, “Who do people say that the Son of Man is?” And they said, “Some say John the Baptist; and others, Elijah; and still others, Jeremiah, or one of the other prophets.” He *said to them, “But who do you yourselves say that I am?” Simon Peter answered, “You are the Christ, the Son of the living God.” And Jesus said to him, “Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven. And I also say to you that you are Peter, and upon this rock I will build My church; and the gates of Hades will not overpower it...

From that time Jesus began to point out to His disciples that it was necessary for Him to go to Jerusalem and to suffer many things from the elders, chief priests, and scribes, and to be killed, and to be raised up on the third day. And yet Peter took Him aside and began to rebuke Him, saying, “God forbid it, Lord! This shall 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 not setting your mind on God’s purposes, but men’s.”
