Pool of Siloam
As he went along, he saw a man blind from birth. His disciples asked him, “Rabbi, who sinned, this man or his parents, that he was born blind?” “Neither this man nor his parents sinned,” said Jesus, “but this happened so that the works of God might be displayed in him. As long as it is day, we must do the works of him who sent me. Night is coming, when no one can work. While I am in the world, I am the light of the world.” After saying this, he spat on the ground, made some mud with the saliva and put it on the man’s eyes. “Go,” he told him, “wash in the Pool of Siloam” (this word means “Sent”). So the man went and washed, and came home seeing.
The account of the healing of the man who had been blind since birth (John 9:1-41) is one of the longest Gospel narratives of any of the miracles of Jesus.
