Biblical Archaeology: The Pool of Siloam

Most readers of the New Testament remember the dramatic story of how Jesus healed a blind man at the Pool of Siloam in Jerusalem (John 9:1–11). The pool was a major feature of ancient Jerusalem as it was fed by spring waters which qualified it for use as a mikveh for ritual bathing. That is why Jesus told the man he healed “ ‘Go …wash in the Pool of Siloam’ … So the man went and washed, and came home seeing” (vs. 7).

The pool’s history predates the time of Jesus by many centuries, however. It was constructed  by Hezekiah, the king of Judah in the  eighth century B.C., who anticipated a siege against Jerusalem by invading Assyrian armies  (2 Kings 20:20).  So the pool began as an important source of fresh water for the inhabitants of ancient Jerusalem, and probably only later began to be used as a place of ritual bathing, as it evidently was in Jesus’ time.

Although the history of the Pool of Siloam was well known, its exact location was not.   In 1880, the famous Siloam Inscription was discovered carved on the wall inside the water tunnel made by Hezekiah which led to the Pool of Siloam. The ancient Hebrew inscription records how the tunnel was constructed by digging from opposite ends and meeting in the middle. So the tunnel that supplied the pool’s water was known, yet the pool itself remained buried. 

Traditionally, the site of the Siloam Pool was the pool and church that were built by the Byzantine empress Eudocia (c. A.D. 400–460) to commemorate the miracle recounted in the New Testament. However, the exact location of the original pool as it existed during the time of Jesus remained a mystery until only recently.

British-American excavations conducted in the 1890’s led to the uncovering of some of the steps of the pool itself near the City of David to the southeast of the traditional site, and in the 1960’s famed British archeologist Kathleen Kenyon found more of the steps. In 2004, municipal water company work exposed additional steps and subsequently Israel’s archaeological authority, the IAA, began systematic excavation of the area.  Now the IAA has announced that it has confirmed that the pool was larger than previously thought – 225 feet wide and approximately 1.25 acres in area – and that steps existed on at least three sides of the pool, allowing visitors to sit and immerse themselves in the water.  IAA also announced that a good portion of the pool is now excavated, and it is hoped that it will soon be opened to the public for the first time in 2,000 years.

The Pool of Siloam, “Hezekiah’s Tunnel,” and the texts and finds that have been unearthed in and around these sites  are of great importance for understanding and establishing the biblical stories.  According to Professor Gershon Galil, head of the Institute for Biblical Studies and Ancient History at Haifa University in Isarel, these finds “support the claim that scriptures in the Book of Kings are based on texts originating from chronicles and royal inscriptions and that the Bible reflects historical reality and not imagination.”

The Pool of Siloam is also important as part of the wider context of ancient evidence of the Jerusalem of Jesus’ time.  According to the City of David Foundation’s Ze’ev Orenstein, “The half-mile running through the City of David, from the Pool of Siloam in the south, continuing along the Pilgrimage Road, up to the footsteps of the Western Wall, Southern Steps, and Temple Mount, represents the most [religiously] significant half-mile on the planet.”  Archaeology continues to recover the buried world of the Old and New Testament stories, and – as Orenstein affirms – soon visitors to the area will be able to “see with their own eyes, touch with their own hands, and walk with their own feet upon the very stones” described in those stories.
