John 1:36 In-Context

34 "This I have seen, and I have become a witness that He is the Son of God."

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

36 when he saw Jesus passing by, and said, "Look! that is the Lamb of God!"

37 The two disciples heard his exclamation, and they followed Jesus.

38 Then Jesus turned round, and seeing them following He asked them, "What is your wish?" "Rabbi," they replied--`Rabbi' means `Teacher' --"where are you staying?"
