João 9:8

The neighbors therefore, and they that saw him aforetime, that he was a beggar, said, Is not this he that begged?

For thirty years, or more, the blind person of that community had been observed by all; and suddenly he was whole, able to see as well as anyone! Such a wonder set the whole community in a ferment. Everybody knew the blind beggar with his cup in a conspicuous place every day; and the amazed neighbors' question of his identity, probably resulted from the change in the man's personality caused by the marvelous gift of sight. Despite the change his identity was absolutely certain.
