Matthew 16:15-20

He saith unto them, But who say ye that I am? And Simon Peter answered and said, Thou art the Christ, the Son of the living God. And Jesus answered and said unto him, Blessed art thou, Simon Bar-Jonah: for flesh and blood hath not revealed it unto thee, but my Father who is in heaven. And I also say unto thee, that thou art Peter, and upon this rock I will build my church; and the gates of Hades shall not prevail against it. 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. Then charged he the disciples that they should tell no man that he was the Christ.
