For flesh and blood has not revealed this to you, but my Father who is in heaven. 18And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it. 19I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven."
