Each word adds to the dimension of New Testament miracles. A street sign is not the street, but it points beyond the street that it identifies. The events of the New Testament are not to be seen as events pointing to themselves, but as pointing beyond themselves to show that God approved of a man and His message. The word reflects the source of the miraculous event.
