At The Pool Of Siloam
This Sabbath morning, as Jesus and his two apostles drew near the temple, they encountered a well-known beggar, a man who had been born blind, sitting at his usual place.
As the Master stood there before the blind man, engrossed in deep thought, Nathaniel asked "Master, who did sin, this man or his parents, that he should be born blind?"
Said the Master: "Neither did this man sin nor his parents…This blindness has come upon him in the natural course of events…"
When Jesus had spoken, he said to Nathaniel and Thomas: "Let us create the sight of this blind man on this Sabbath day that the scribes and Pharisees may have the full occasion which they seek for accusing the Son of Man." Then, stooping over, he spat on the ground and mixed the clay with the spittle, and speaking of all this so that the blind man could hear, he went up to Josiah and put the clay over his sightless eyes, saying: "Go, my son, wash away this clay in the Pool of Siloam, and immediately you shall receive your sight." And when Josiah had so washed in the pool of Siloam, he returned to his friends and family, seeing.
Jesus gave this man his sight by miraculous working for the prime purpose of making this act an open challenge to the Sanhedrin and all the Jewish teachers and religious leaders. This was his way of proclaiming an open break with the Pharisees.
