John 1:29-42 Revised Standard Version (RSV)
The Lamb of God
29 The next day he saw Jesus coming toward him, and said, “Behold, the Lamb of God, who takes away the sin of the world! 30 This is he of whom I said, ‘After me comes a man who ranks before me, for he was before me.’ 31 I myself did not know him; but for this I came baptizing with water, that he might be revealed to Israel.” 32 And John bore witness, “I saw the Spirit descend as a dove from heaven, and it remained on him. 33 I myself did not know him; but he who sent me to baptize with water said to me, ‘He on whom you see the Spirit descend and remain, this is he who baptizes with the Holy Spirit.’ 34 And I have seen and have borne witness that this is the Son of God.”
The First Disciples of Jesus
35 The next day again 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 say this, and they followed Jesus. 38 Jesus turned, and saw them following, and said to them, “What do you seek?” And they said to him, “Rabbi” (which means 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, for it was about the tenth hour. 40 One of the two who heard John speak, and followed him, was Andrew, Simon Peter’s brother. 41 He first found his brother Simon, and said to him, “We have found the Messiah” (which means Christ). 42 He brought him to Jesus. Jesus looked at him, and said, “So you are Simon the son of John? You shall be called Cephas” (which means Peter[a]).
