'Clay' in the Bible

These things saying, he spat on the ground, and made clay of the spittle, and rubbed the clay on the eyes of the blind man, and said to him,

he answered and said, 'A man called Jesus made clay, and rubbed my eyes, and said to me, Go away to the pool of Siloam, and wash; and having gone away and having washed, I received sight;'

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

Again, therefore, the Pharisees also were asking him how he received sight, and he said to them, 'Clay he did put upon my eyes, and I did wash -- and I see.'

hath not the potter authority over the clay, out of the same lump to make the one vessel to honour, and the one to dishonour?
