Matthew 16:5-18

And the disciples came to the other side of the sea, but they had forgotten to bring any bread. And Jesus said to them, “Watch out and beware of the leaven of the Pharisees and Sadducees.” They began to discuss this among themselves, saying, “He said that because we did not bring any bread.” But Jesus, aware of this, said, “You men of little faith, why are you discussing among yourselves the fact that you have no bread? Do you not yet understand nor remember the five loaves of the five thousand, and how many baskets you picked up? Nor the seven loaves of the four thousand, and how many large baskets you picked up? How is it that you do not understand that I did not speak to you about bread? But beware of the leaven of the Pharisees and Sadducees.” Then they understood that He did not say to beware of the leaven of bread, but of the teaching of the Pharisees and Sadducees. Now when Jesus came into the region of Caesarea Philippi, He was asking His disciples, “Who do people say that the Son of Man is?” And they said, “Some say John the Baptist; and others, Elijah; and still others, Jeremiah, or one of the other prophets.” He *said to them, “But who do you yourselves say that I am?” Simon Peter answered, “You are the Christ, the Son of the living God.” And Jesus said to him, “Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven. And I also say to you that you are Peter, and upon this rock I will build My church; and the gates of Hades will not overpower it.
