John 3:22-30 New Revised Standard Version (NRSV)
Jesus and John the Baptist
22 After this Jesus and his disciples went into the Judean countryside, and he spent some time there with them and baptized. 23 John also was baptizing at Aenon near Salim because water was abundant there; and people kept coming and were being baptized 24 —John, of course, had not yet been thrown into prison.
25 Now a discussion about purification arose between John’s disciples and a Jew.[a] 26 They came to John and said to him, “Rabbi, the one who was with you across the Jordan, to whom you testified, here he is baptizing, and all are going to him.” 27 John answered, “No one can receive anything except what has been given from heaven. 28 You yourselves are my witnesses that I said, ‘I am not the Messiah,[b] but I have been sent ahead of him.’ 29 He who has the bride is the bridegroom. The friend of the bridegroom, who stands and hears him, rejoices greatly at the bridegroom’s voice. For this reason my joy has been fulfilled. 30 He must increase, but I must decrease.”[c]
