As Jesus went along, he saw a man who had been blind from birth. His disciples asked him, “Rabbi, who sinned, this man or his parents, for him to have been born blind. “Neither he nor his parents sinned,” Jesus answered, “He was born blind so that the works of God might be displayed in him.” As long as the day lasts, I must carry out the work of the one who sent me; the night will soon be here when no one can work. As long as I am in the world, I am the light of the world.”
Having said this, he spat on the ground, made a paste with the spittle, put this over the eyes of the blind man and said to him, “Go wash in the Pool of Siloam (a name that means sent).” So the blind man went off and washed himself and came away with his sight restored.
