Matthew 16:12-16

Then understood they how that he bade them not beware of the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees.

When Jesus came into the coasts of Caesarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am?

And they said, Some say that thou art John the Baptist: some, Elias; and others, Jeremias, or one of the prophets.

He saith unto them, But whom say ye that I am?

And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
