Jeremiah 31:31-34 New Revised Standard Version, Anglicised Catholic Edition (NRSVACE)
A New Covenant
31 The days are surely coming, says the Lord, when I will make a new covenant with the house of Israel and the house of Judah. 32 It will not be like the covenant that I made with their ancestors when I took them by the hand to bring them out of the land of Egypt—a covenant that they broke, though I was their husband,[a] says the Lord. 33 But this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put my law within them, and I will write it on their hearts; and I will be their God, and they shall be my people. 34 No longer shall they teach one another, or say to each other, ‘Know the Lord’, for they shall all know me, from the least of them to the greatest, says the Lord; for I will forgive their iniquity, and remember their sin no more.

Peter’s Declaration about Jesus
13 Now when Jesus came into the district of Caesarea Philippi, he asked his disciples, ‘Who do people say that the Son of Man is?’ 14 And they said, ‘Some say John the Baptist, but others Elijah, and still others Jeremiah or one of the prophets.’ 15 He said to them, ‘But who do you say that I am?’ 16 Simon Peter answered, ‘You are the Messiah,[a] the Son of the living God.’ 17 And Jesus answered him, ‘Blessed are you, Simon son of Jonah! For flesh and blood has not revealed this to you, but my Father in heaven. 18 And I tell you, you are Peter,[b] and on this rock[c] I will build my church, and the gates of Hades will not prevail against it. 19 I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.’ 20 Then he sternly ordered the disciples not to tell anyone that he was[d] the Messiah.[e]
Jesus Foretells His Death and Resurrection
21 From that time on, Jesus began to show his disciples that he must go to Jerusalem and undergo great suffering at the hands of the elders and chief priests and scribes, and be killed, and on the third day be raised. 22 And Peter took him aside and began to rebuke him, saying, ‘God forbid it, Lord! This must never happen to you.’ 23 But he turned and said to Peter, ‘Get behind me, Satan! You are a stumbling-block to me; for you are setting your mind not on divine things but on human things.’
