Matthew 16:18

15 He says to them, But who do you say that I am?

16 And Simon Peter made answer and said, You are the Christ, the Son of the living God.

17 And Jesus made answer and said to him, A blessing on you, Simon Bar-jonah: because this knowledge has not come to you from flesh and blood, but from my Father in heaven.

18 And I say to you that you are Peter, and on this rock will my church be based, and the doors of hell will not overcome it.

19 I will give to you the keys of the kingdom of heaven: and whatever is fixed by you on earth will be fixed in heaven: and whatever you make free on earth will be made free in heaven.

20 Then he gave orders to the disciples to give no man word that he was the Christ.

21 From that time Jesus went on to make clear to his disciples how he would have to go up to Jerusalem, and undergo much at the hands of those in authority and the chief priests and scribes, and be put to death, and the third day come again from the dead.
