Matthew 16:18-21

So I tell you, you are Peter. On this rock I will build my church, and the power of death will not be able to defeat it. I will give you the keys of the kingdom of heaven; the things you don’t allow on earth will be the things that God does not allow, and the things you allow on earth will be the things that God allows.” Then Jesus warned his followers not to tell anyone he was the Christ. From that time on Jesus began telling his followers that he must go to Jerusalem, where the Jewish elders, the leading priests, and the teachers of the law would make him suffer many things. He told them he must be killed and then be raised from the dead on the third day.
