John 1:35-40

35Again, on the morrow, there stood John and two of his disciples.

36And, looking at Jesus as he walked, he says, Behold the Lamb of 1God.

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

38But Jesus having turned, and seeing them following, says to them, What seek ye? And they said to him, Rabbi (which, being interpreted, signifies Teacher), where abidest thou?

39He says to them, Come and see. They went therefore, and saw where he abode; and they abode with him that day. It was about the tenth hour.

40Andrew, the brother of Simon Peter, was one of the two who heard [this] from John and followed him.
