'Clay' in the Bible

After thus speaking, He spat on the ground, and then, kneading the dust and spittle into clay, He smeared the clay over the man's eyes and said to him,

"He whose name is Jesus," he answered, "made clay and smeared my eyes with it, and then told me to go to Siloam and wash. So I went and washed and obtained sight."

Now the day on which Jesus made the clay and opened the man's eyes was the Sabbath.

So the Pharisees renewed their questioning as to how he had obtained his sight. "He put clay on my eyes," he replied, "and I washed, and now I can see."
