John 1:37

34 And I have seen, and have borne witness that this is the Son of God.

35 Again on the morrow John was standing, and two of his disciples;

36 and he looked upon Jesus as he walked, and saith, Behold, the Lamb of God!

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

38 And Jesus turned, and beheld them following, and saith unto them, What seek ye? And they said unto him, Rabbi (which is to say, being interpreted, Teacher), where abideth thou?

39 He saith unto them, Come, and ye shall see. They came therefore and saw where he abode; and they abode with him that day: it was about the tenth hour.

40 One of the two that heard John [speak], and followed him, was Andrew, Simon Peter`s brother.
