Mark 8:27-30

²⁷And Jesus went forth, and his disciples, into the villages of Caesarea Philippi: and on the way he asked his disciples, saying unto them, Who do men say that I am? ²⁸And they answered, John the Baptist; and others, Elijah; but others, One of the prophets. ²⁹And he saith unto them, But who say ye that I am? And Peter answereth and saith unto him, Thou art the Christ. ³⁰And he charged them that they should tell no man of him.
