Matthew 16:17

14 and they said, `Some, John the Baptist, and others, Elijah, and others, Jeremiah, or one of the prophets.`

15 He saith to them, `And ye -- who do ye say me to be?`

16 and Simon Peter answering said, `Thou art the Christ, the Son of the living God.`

17 And Jesus answering said to him, `Happy art thou, Simon Bar-Jona, because flesh and blood did not reveal [it] to thee, but my Father who is in the heavens.

18 `And I also say to thee, that thou art a rock, and upon this rock I will build my assembly, and gates of Hades shall not prevail against it;

19 and I will give to thee the keys of the reign of the heavens, and whatever thou mayest bind upon the earth shall be having been bound in the heavens, and whatever thou mayest loose upon the earth shall be having been loosed in the heavens.`

20 Then did he charge his disciples that they may say to no one that he is Jesus the Christ.
