Matthew 16:18-19

And I say also unto thee, That thou art Peter, a small rock and upon the large rock I will build my congregation, {Gr. ekklesia – called out ones} and the gates of Hades shall not prevail against her. And I will give unto thee the keys of the kingdom of the heavens, and whatever thou shalt bind on the earth shall be bound in the heavens, and whatever thou shalt loose on the earth shall be loosed in the heaven.
