'Sight' in the Bible

He answered and said, A man that is called Jesus made clay, and anointed mine eyes, and said unto me, Go to the pool of Siloam, and wash: and I went and washed, and I received sight.

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.

But the Jews did not believe concerning him, that he had been blind, and received his sight, until they called the parents of him that had received his sight.
