John 1:40-42

40Andrew was one of the two disciples who had followed Jesus. They had heard what John had said about Jesus. Andrew was Simon Peter's brother.

41The first thing that Andrew did was to find his brother, Simon. Andrew said to Simon, ‘We have found the Messiah.’ (‘Messiah’ and ‘Christ’ mean the same.)

42Then he brought Simon to Jesus. Jesus looked at Simon and he said, ‘You are Simon, John's son. Your name will be Cephas.’ This name is the same as Peter, which means ‘rock’.
