John 3:27-30 New American Bible, Revised Edition (NABRE)

27. John answered and said, “No one can receive anything except what has been given him from heaven.

28. You yourselves can testify that I said [that] I am not the Messiah, but that I was sent before him.

29. The one who has the bride is the bridegroom; the best man, who stands and listens to him, rejoices greatly at the bridegroom’s voice. So this joy of mine has been made complete.

30. He must increase; I must decrease.”
