In June 2004, construction workers at the southern end of the City of David. They were repairing a water pipe and ultimately helped discover the Pool of Siloam, a miraculous site read in John 9. In the last week of August 2025, the Israel Antiquities Authority announced that the pipe is a 39-foot-tall structure radiocarbon-dated to be approximately 2,800 years old.
Breaking News: That timeline aligns with the story of the man born blind at birth, who became a stop on Jesus of Nazareth's remarkable ministry.
Science and faith are two distinct and separate fields of study. Technically, the phrase "science proves faith" is unnatural. Science is limited to investigating the natural, observable world. The places where the supernatural aspects of miracles, spiritual warfare, and the Holy Ghost are outside the purview of investigation.
However, there have been times when a field of science -- like archaeology -- can prove a story related to faith -- like the discovery of the Pool of Siloam -- and galvanize science and faith to evangelize the masses. This discovery is one of those stories and something that definitely hits "close to home."
This substantial wall, discovered in Jerusalem's City of David, did more than dam up water flow. It released the reality of a miracle first discovered in John 9.
Now as Jesus passed by, He saw a man who was blind from birth. And His disciples asked Him, saying, "Rabbi, who sinned, this man or his parents, that he was born blind?"
...When He had said these things, He spat on the ground and made clay with the saliva; and He anointed the eyes of the blind man with the clay. And He said to him, "Go, wash in the pool of Siloam" (which is translated, Sent). So he went and washed, and came back seeing.
...Therefore they said to [the blind man at the Pool of Siloam], "How were your eyes opened?" He answered and said, "A Man called Jesus made clay and anointed my eyes and said to me, 'Go to the pool of Siloam and wash.' So I went and washed, and I received sight."
(John 9:1-2, 6-7, 10-11 NKJV)
Excavation director Itamar Berko of the Israel Antiquities Authority (IAA) spoke to the Telegraph (UK). He said the discovery provided a "tangible" link to the place described in scripture. The full dam is 26' wide and over 68' long. Its purpose was to collect and form the Pool of Siloam.
"If until today we could only read in the Biblical text about the existence of the Pool of Siloam, now we can see its tangible remnants and its beginning," Breko said. "Behind us is a monumental dam wall, enormous in size, over 11 metres high, dated to 2,800 years ago during the First Temple period, in the time of kings Joash and Amaziah."
The IAA notes this discovery of biblical proportions was part of an engineering complex. Its purpose was to capture water from the Gihon Spring. From there, it was channeled through the Tyropoeon Valley to the Kidron Stream.
This is the First Temple period (1000 to 586 BCE). Solomon's Temple was the hub of devotion to God and the center of administration for the people. It spanned the United Kingdom of Israel to the Kingdom of Judah. In biblical stories, that's the reign of Hezekiah and Solomon. It's also the Babylonian conquest of Jerusalem and the destruction of the Temple.
The IAA notes that slaves during the reigns of King Joash and Amaziah built this wall. With all these Old Testament references, where is the Pool of Siloam? It is in 2 Kings.
The rest of the events of Hezekiah's reign and all his accomplishments, including how he built a pool and conduit to bring water into the city, are recorded in the scroll called the Annals of the Kings of Judah. 2 Kings 20:20 (NASB)
The "conduit" is a tunnel that brought water from the Gihon Spring into this pool within the walls of Jerusalem. Historical records by Flavius Josephus state that the Pool of Siloam was located in the southeast corner of the wall of Jerusalem at a turn. That's where excavators discovered this pool, which kicked off the massive project of discovery.
Researchers note that this First Temple dam, discovered in Jerusalem's City of David, was built between 805 and 795 BCE. That's 805 BC to 2025 AD, which is 2,829 years. You know? The same timeframe of radiocarbon dating for the pipe, the wall, and this dam?
