13 They brought to the Pharisees him that aforetime was blind.
14 And it was the sabbath day when Jesus made the clay, and opened his eyes.
15 Then again the Pharisees also asked him how he had received his sight. He said unto them, He put clay upon mine eyes, and I washed, and do see.
16 Therefore said some of the Pharisees, This man is not of God, because he keepeth not the sabbath day. Others said, How can a man that is a sinner do such miracles? And there was a division among them.
17 They say unto the blind man again, What sayest thou of him, that he hath opened thine eyes? He said, He is a prophet.
