Mark 8:30

And they answered, John the Baptist; but some say, Elias; and others, One of the prophets.

And he saith unto them, But whom say ye that I am? And Peter answereth and saith unto him, Thou art the Christ.

And he began to teach them, that the Son of man must suffer many things, and be rejected of the elders, and of the chief priests, and scribes, and be killed, and after three days rise again.

And he spake that saying openly. And Peter took him, and began to rebuke him.
