Charles Spurgeon Commentary John 8:1-3

"but Jesus went unto the mount of Olives. And early in the morning he came again into the temple, and all the people came unto him; and he sat down, and taught them. And the scribes and the Pharisees bring a woman taken in adultery; and having set her in the midst," — John 8:1-3 (ASV)

And as Jesus passed by, he saw a man which was blind from his birth. And his disciples asked him, saying, Master, who did sin, this man, or his parents, that he was born blind? Jesus answered, Neither hath this man sinned, nor his parents:

That is, the sin of the man or of his parents was not the cause of his being blind.
