John 1:40-42

40 One of the two who heard John, and followed him, was Andrew, Simon Peter's brother.

41 He first found his own brother, Simon, and said to him, "We have found the Messiah!" (which is, being interpreted, Christ).

42 He brought him to Jesus. Jesus looked at him, and said, "You are Simon the son of John. You shall be called Cephas" (which is by interpretation, Peter).
