'Clay' in the Bible

When He had said this, He spat on the ground, and made clay of the spittle, and applied the clay to his eyes,

He answered, “The man who is called Jesus made clay, and anointed my eyes, and said to me, ‘Go to Siloam and wash’; so I went away and washed, and I received sight.”

Now it was a Sabbath on the day when Jesus made the clay and opened his eyes.

Then the Pharisees also were asking him again how he received his sight. And he said to them, “He applied clay to my eyes, and I washed, and I see.”

Or does not the potter have a right over the clay, to make from the same lump one vessel for honorable use and another for common use?
