John 1:37

34 I have seen, and have testified that this is the Son of God."

35 Again, on the next day, John was standing with two of his disciples,

36 and he looked at Jesus as he walked, and said, "Behold, the Lamb of God!"

37 The two disciples heard him speak, and they followed Jesus.

38 Jesus turned, and saw them following, and said to them, "What are you looking for?" They said to him, "Rabbi" (which is to say, being interpreted, Teacher), "where are you staying?"

39 He said to them, "Come, and see." They came and saw where he was staying, and they stayed with him that day. It was about the tenth hour.

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