Mark 8:27-33 

27 Jesus set out with his disciples for the villages around Caesarea Philip pi; and on the way he asked them, “Who do people say I am?”

28 And they told him, “Some say, you are John the Baptist; others say, you are Elijah or one of the prophets.” Then Jesus asked them,

29 “But you, who do you say I am?” Peter answered, “You are the Messiah.”

30 And he ordered them not to tell anyone about him.

31 Jesus then began to teach them that the Son of Man had to suffer many things and be rejected by the elders, the chief priests and the teachers of the law. He would be killed, and after three days rise again.

32 Jesus said all this quite openly, so that Peter took him aside and began to protest strongly.

33 But Jesus, turning around, and looking at his disciples, rebuked Peter, saying, “Get behind me, Satan! You are thinking not as God does, but as people do.”
