Many of Jesus' acts are directly linked to Jewish rituals, and the miracle of the blind man is an example. The man was undergoing ritual immersion in the Siloam Pool for entry into the temple compound, and Jesus used the occasion to cure his blindness (John 9: 1-7).

In the last four months, archeologists have revealed the pool's 50-metre length and a channel that brought water from the Silwan spring to the pool. In the past week, a section of stone road that led from the pool to the Jewish Temple was uncovered.

"The moment that we revealed and discovered this four months ago, we were 100 per cent sure it was the Siloam Pool," said Eli Shukron, one of the archeologists on the dig.

"We know today that the Siloam Pool is connected to the Temple Mount. There is a road that connects between the two elements. The entire system is clearer today," Shukron said.

Stephen Pfann, a Bible scholar, said that the pool's waters were considered so pure that they could purify even a leper.

Pfann said Jesus likely chose to cure the blind man using the purest water available because people with any disabilities were barred from the temple.

"The whole point is that people will not only be healed physically but also healed spiritually," he said. "This discovery helps bring the Gospel alive in the context of Jewish practice."

The archeologists excavating the site are with the Israeli government's Antiquities Authority. They found biblical-era coins marked with ancient Jewish writing, along with pieces of broken pottery -- including a stone bottle cork -- helping them confirm that the area was the biblical Siloam Pool.

The stone-lined pool has steps leading into it from all sides, said Ronny Reich, a University of Haifa archeologist. One side of the pool, two corners, a part of the esplanade around it and the water channel leading to it have been uncovered, he said.

Jesus, according to the New Testament, put clay on a blind man's eyes and then sent him to wash them out in the pool's purifying waters, giving him sight.

Jews, who traditionally made three pilgrimages a year to Jerusalem, would immerse themselves in the Siloam Pool before heading down the stone pathway to the temple. They also used the pool for drinking water and camped around it.

"Jesus was a pilgrim in Jerusalem ... so this would be a natural place for him to be ... enjoying the water supply," Reich said.

The Israeli Antiquities Authority is negotiating with the Greek Orthodox Church, which owns the land, to continue the dig. Archeologists believe the pool is about 50 metres wide and is under the thick green covering of an overgrown vegetable garden and several large trees.

Three-metre-high stone walls topped by old sewage and drainage pipes separate the new discovery and the pool's stone steps, uncovered in the 1960s. Now archeologists hope to remove the old pipes and connect the esplanade and water channel to the steps that lead into the pool.

"Here we can judge and see how large it is -- the grandeur of the city in those days," Reich said.
