John 1:38-42

And Jesus turned, and beheld them following, and saith unto them, What seek ye? And they said unto him, Rabbi (which is to say, being interpreted, Teacher), where abidest thou? He saith unto them, Come, and ye shall see. They came therefore and saw where he abode; and they abode with him that day: it was about the tenth hour. One of the two that heard John speak, and followed him, was Andrew, Simon Peter’s brother. He findeth first his own brother Simon, and saith unto him, We have found the Messiah (which is, being interpreted, Christ). He brought him unto Jesus. Jesus looked upon him, and said, Thou art Simon the son of John: thou shalt be called Cephas (which is by interpretation, Peter).
