St John 1:40-42

And Andrew, the brother of Simon Peter, was one of the two who had heard of John, and followed him. He findeth first his brother Simon, and saith to him: We have found the Messias, which is, being interpreted, the Christ. And he brought him to Jesus. And Jesus looking upon him, said: Thou art Simon the son of Jona: thou shalt be called Cephas, which is interpreted Peter.
