'Clay' in the Bible

[When he] had said these [things], he spat on the ground and made clay with the saliva, and smeared the clay on his eyes.

He replied, "The man who is called Jesus made clay and smeared [it] on my eyes and said to me, 'Go to Siloam and wash!' So I went, and I washed, [and] I received sight."

(Now the day on which Jesus made the clay and opened his eyes was the Sabbath.)

So the Pharisees also were asking him again how he received sight. And he said to them, "He put clay on my eyes, and I washed, and I see."
