Some time ago, we walked through Hezekiah’s Tunnel, the channel two teams of workers cut through solid rock around 700 BC to bring the waters of the Gihon Spring inside Jerusalem’s walls before the Assyrians arrived. Where did that water go? It flowed a third of a mile under the city and emptied into a pool at the southern end of the City of David. That pool was called Siloam. Seven centuries later, a blind man would wash his eyes in that same water and see for the first time in his life. For a long time, no one was sure where that pool was. Visitors to Jerusalem were shown a small pool near the end of Hezekiah’s Tunnel, built in the Byzantine period, centuries after Jesus, and some scholars doubted that John’s Pool of Siloam had ever been a real place at all. John’s Gospel is full of symbolism, they argued, and a pool whose name means “Sent,” where a man is sent to wash, sounded more like a theological image than a location. Then, in June 2004, workers from the Jerusalem water authority were digging to repair a sewer pipe just south of the old City of David. Their equipment struck stone steps. Archaeologists Eli Shukron and Ronny Reich were called in, and as they excavated, more steps appeared, broad stone stairs descending in stages toward what had once been water. They had found a large public pool from the time of Jesus, a short distance from the Byzantine pool everyone had been visiting. The dating came from coins. Coins were found sealed in the plaster of the pool’s construction, and others were found on the steps from the years of the Jewish revolt against Rome, AD 66 to 70. That means the pool was in use in the generation of Jesus and remained in use until Jerusalem was destroyed. After that, the pool was buried and forgotten until a broken sewer pipe brought it back to light. Ronny Reich, one of the excavators and not a man known for making religious claims, said there was no doubt that this was the Pool of Siloam of Jesus’ time. Now read John 9 with that place in mind. It begins with Jesus passing a man who had been blind from birth. The disciples ask the question everyone in that culture would ask: “Rabbi, who sinned, this man or his parents, that he was born blind?” In their minds, suffering must be punishment. Jesus refuses the premise entirely: neither this man nor his parents, “but that the works of God might be displayed in him.” Then Jesus does something no other healing in the Gospels does quite this way. He spits on the ground, makes mud with the saliva, and spreads it on the man’s eyes. Early Christian writers noticed what this echoes. In Genesis, God formed man from the dust of the ground. Here Jesus takes the dust of the ground in His hands and forms new eyes for a man who was born without sight. The Creator was doing in front of them what He had done at the beginning. Then He tells him, “Go, wash in the pool of Siloam.” And John stops to translate the name for his readers: Siloam means “Sent.” This matters because throughout John’s Gospel, Jesus describes Himself again and again as the One sent by the Father. The man was sent to the pool called Sent by the One who was sent. The man went, washed, and came back seeing. The location gives the walk real weight. The pool lay at the bottom of the city, down the slope of the City of David, at the southern edge of Jerusalem. A man blind from birth, with mud on his eyes, had to make his way down through the streets to reach it, without anyone telling us he was led. The healing did not happen when Jesus touched him. It happened when he obeyed. What follows is one of the longest and most dramatic scenes in the Gospels, and it is almost comic. The man’s neighbors cannot agree whether he is the same person. The Pharisees interrogate him because the healing happened on the Sabbath. They call in his parents, who are so afraid of being expelled from the synagogue that they will only say, “He is of age; ask him.” The Pharisees bring the man back and demand that he call Jesus a sinner. He gives them one of the great answers in all of Scripture: “Whether he is a sinner I do not know. One thing I do know, that though I was blind, now I see.” They keep pushing, and he keeps getting bolder. When they ask him to repeat the story yet again, he asks whether they want to become Jesus’ disciples too. Then the man who had begged for his whole life by the roadside lectures the religious authorities of Jerusalem: never since the world began has anyone opened the eyes of a man born blind; if this man were not from God, He could do nothing. They answer him with contempt, “You were born in utter sin, and would you teach us?” and they throw him out. The account does not end there. John says that Jesus heard they had cast him out, and went and found him. The man had never actually seen Jesus. When Jesus sent him to the pool, he was still blind. Now Jesus asks him, “Do you believe in the Son of Man?” The man answers, “Who is he, sir, that I may believe in him?” Jesus says, “You have seen him, and it is he who is speaking to you.” The man says, “Lord, I believe,” and he worships Him. The first face he ever saw that he knew to look for was the face of God. There is one more layer of context. This healing comes right after the Feast of Tabernacles in John 7 and 8. During that feast, according to Jewish tradition preserved in the Mishnah, priests walked in procession down to the Pool of Siloam each morning, filled a golden pitcher with its water, and carried it up to the temple to pour out at the altar, while great lamps were lit in the temple courts at night. In the middle of that feast, Jesus stood and cried out, “If anyone thirsts, let him come to me and drink,” and then, “I am the light of the world.” Now, a few verses later, He says it again, “As long as I am in the world, I am the light of the world,” and sends a blind man to the pool of the festival water to receive light. He was not just quoting the festival. He was claiming to be what it was pointing to. People say that John’s Gospel is a late theological reflection, more interested in symbols than places. But the symbols are standing on real stone. The pool called Sent was a real pool, fed by a real tunnel dug by a real king, with steps you can walk down today in Jerusalem. A broken sewer pipe uncovered the place where a beggar washed mud out of his eyes and saw the world for the first time. Maybe you have been told that your suffering is your fault, that someone must have sinned for life to be this dark. Hear what Jesus said: this is where the works of God will be displayed. Maybe you have been pushed out of a place you belonged because of what you know He did for you. He goes looking for the ones who are cast out. And if you are still in the dark, He is still sending: go and wash. Obey what He has said, even before you can see. One thing I know: I was blind, but now I see. Jesus is the Light of the World.
