'Clay' in the Bible

When he had thus spoken, he spat on the ground, and made clay of the spittle, and he anointed the eyes of the blind man with the clay,

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.

And it was the sabbath day when Jesus made the clay, and opened his eyes.

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.

Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour?
