Mark 8:30-33

And he charged them that they should tell no man of him. And he began to teach them, that the Son of man must suffer many things, and be rejected by the elders, and the chief priests, and the scribes, and be killed, and after three days rise again. And he spake the saying openly. And Peter took him, and began to rebuke him. But he turning about, and seeing his disciples, rebuked Peter, and saith, Get thee behind me, Satan; for thou mindest not the things of God, but the things of men.
