Charles Spurgeon Commentary John 8:8-9

"And again he stooped down, and with his finger wrote on the ground. And they, when they heard it, went out one by one, beginning from the eldest, [even] unto the last: and Jesus was left alone, and the woman, where she was, in the midst." — John 8:8-9 (ASV)

The neighbours therefore, and they which before had seen him that he was blind, said, Is not this he that sat and begged? Some said, This is he; others said, He is like him: but he said, I am he.

There is an end to all question about the matter; he says, "I am the very man." No one knew this better than he did, and therefore he was the one to say it.
