Matthew 16:15

11How is it that you don’t perceive that I didn’t speak to you concerning bread? But beware of the yeast of the Pharisees and Sadducees.”

12Then they understood that he didn’t tell them to beware of the yeast of bread, but of the teaching of the Pharisees and Sadducees.

13Now when Jesus came into the parts of Caesarea Philippi, he asked his disciples, saying, “Who do men say that I, the Son of Man, am?”

14They said, “Some say John the Baptizer, some, Elijah, and others, Jeremiah or one of the prophets.”

15He said to them, “But who do you say that I am?”

16Simon Peter answered, “You are the Christ, the Son of the living God.”

17Jesus answered him, “Blessed are you, Simon Bar Jonah, for flesh and blood has not revealed this to you, but my Father who is in heaven.

18I also tell you that you are Peter, and on this rock I will build my assembly, and the gates of Hades will not prevail against it.

19I will give to you the keys of the Kingdom of Heaven, and whatever you bind on earth will have been bound in heaven; and whatever you release on earth will have been released in heaven.”
