Matthew 16:13-20 (KJV)
[13] 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?

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

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

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

[17] And Jesus answered and said unto him, Blessed art thou,
Simon Barjona: for flesh and blood hath not revealed it
unto thee, but my Father which is in heaven.

[18] And I say also unto thee, That thou art Peter,
and upon this rock I will build my church; and the
gates of hell shall not prevail against it.

[19] And I will give unto thee the keys of the
kingdom of heaven: and whatsoever thou shalt bind
on earth shall be bound in heaven: and whatsoever
thou shalt loose on earth shall be loosed in heaven.

[20] Then charged he his disciples that they should
tell no man that he was Jesus the Christ.
