John 1:35-40

Again the next day John was standing with two of his disciples, and he looked at Jesus as He walked along, and said, “Look! The Lamb of God!” The two disciples heard him say this, and they followed Jesus. And Jesus turned and saw them following Him, and asked them, “What do you want?” They answered Him, “Rabbi (which translated means Teacher), where are You staying?” He said to them, “Come, and you will see.” So they went [with Him] and saw where He was staying; and they stayed with Him that day, for it was about the tenth hour. One of the two who heard what John said and [as a result] followed Jesus was Andrew, Simon Peter’s brother.
