John 1:35-43

35The next day John was there again with two of his disciples. 36When he saw Jesus passing by, he said, "Look, the Lamb of God!"

37When the two disciples heard him say this, they followed Jesus. 38Turning around, Jesus saw them following and asked, "What do you want?"
They said, "Rabbi" (which means Teacher), "where are you staying?"

39"Come," he replied, "and you will see."
So they went and saw where he was staying, and spent that day with him. It was about the tenth hour.

40Andrew, Simon Peter's brother, was one of the two who heard what John had said and who had followed Jesus. 41The first thing Andrew did was to find his brother Simon and tell him, "We have found the Messiah" (that is, the Christ). 42And he brought him to Jesus.
Jesus looked at him and said, "You are Simon son of John. You will be called Cephas" (which, when translated, is Peter).
Jesus Calls Philip and Nathanael
43The next day Jesus decided to leave for Galilee. Finding Philip, he said to him, "Follow me."
