Matthew 16:13-21 NIV
When Jesus came to the region of Caesarea Philippi, he asked his disciples, “Who do people say the Son of Man is?”
They replied, “Some say John the Baptist; others say Elijah; and still others, Jeremiah or one of the prophets.”
“But what about you?” he asked. “Who do you say I am?”
Simon Peter answered, “You are the Messiah, the Son of the living God.”
Jesus replied, “Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven. And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.” Then he ordered his disciples not to tell anyone that he was the Messiah.
From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, the chief priests and the teachers of the law, and that he must be killed and on the third day be raised to life.
