John 3:26-30

And they came unto John, and said to him, Rabbi, he that was with thee beyond the Jordan, to whom thou hast borne witness, behold, the same baptizeth, and all men come to him. John answered and said, A man can receive nothing, except it have been given him from heaven. Ye yourselves bear me witness, that I said, I am not the Christ, but, that I am sent before him. He that hath the bride is the bridegroom: but the friend of the bridegroom, that standeth and heareth him, rejoiceth greatly because of the bridegroom’s voice: this my joy therefore is made full. He must increase, but I must decrease.
