exposes the strategy that once revived use, from 1000 years prior, of a Bronze Age underground passage - Warrens Shaft System (WSS) to deliver water inside (west) of the wall so that the city could prolong its siege defense against Assyrians and Babylonian enemies.

The mountain city's natural water source was the Gihon Spring, in the eastern escarpment where water exited into a cave just above the valley floor. For the first Bronze Age residents, living on the upper ridge, moving water 60 vertical meters up the escarpment was a major daily undertaking. Back then, supply was regulated by the local kings' whose water carriers would haul water sacks up the escarpment to meet the growing demand further up the ridge.
The east, west and south escarpments, on lower Mount Moriah fall sharply into surrounding valleys that provided a naturally defensive barrier against enemy attack. From the north, on the summit, distant movements could be clearly observed to prepare and repel hostilities. The upper flats, on the lower section of Mount Moriah was ideal to establish a small village and protect its residents, but water presented a major challenge.
Bronze Age occupants had a limited population size, but archaeology for that period suggests more than just local residents helped to construct a secure water carriage system. According to the Hebrew Bible Mount Moriah contained indigenous artifacts that Israelites, after Jacob and 250 years of exile, would have been intent to reclaim along with their inherited land. To improve water security and possibly dissuade an Israelite attack, the residents must have obtained regional labor support from regional allies in order to massively excavate the bedrock of the mountain.
Four significant constructions must be understood in order to interpret ancient events on the mountain and the motivation for theses constructions:
1. The 'Warren's Shaft System' (WSS) - a man-made tunnel rising through the mountain that permitted cool, efficient and protected passage to water carriers. Water was carried from the spring, hauled up to lower level dwellings at the uppermost exit of the system and further up to the city's mountain ridge (a ~60m vertical rise from the water).
2. Double walls - 'W108/W109' were built, east-west up the escarpment using +1 ton boulders carried up a ~30 degree grade and precisely placed to build the staggered walls that stretch ~50 meters uphill at a height of 6-10m. Such a substantial construction required more labor force than the residential capacity of the upper city.
3. The 'Rock-cut Feature' (RCF) - a large quarry, south of W109 left a gaping wound in the bedrock and cut convenient access between Area U's Rock-Cut-Rooms, on the higher slope of the eastern escarpment and the Gihon water source below.
4. The 'Rock-Cut-Rooms' (RCR) - a temple complex of 4 rooms each with a feature dedicated to worship. They include (from north to south) an olive press for pure oil, raised altar platform and liquids channel, matzevah or anointing-pillar and room for slaughtering and processing animal sacrifices.
Ongoing debate about the date of these features leads to consensus that some or all elements, of each feature converge on periods of the Bronze Age, which is sufficient context for this article.
The time-layered system of channels, walls, boulevards, ridges and passages secured water supply for residents who had moved from the valley floor to the mountain ridge. It also served the franchise of the local king.
During the Bronze and early Iron Age produce in the Kidron Valley was grown using the constant flow of water from Channel I or II. At or around the Gihon Spring produce was processed, traded and distributed. There produce and water filled leather sacks would have been loaded on donkey's that traversed up the escarpment into the city. Eventually a walkway and donkey pathway (see image below) eased the 35+ degree climb ~60 vertical meters up the eastern slope. Food trade from other cities, including the coast may also have arrived from the north and west, along convenient routes to the Kidron Valley.

When attacked the terraced path became exposed and water transportation retreated underground to the excavated WSS. Water carriers would carry water sacks through its underground tunnel and haul them up its vertical shaft to a height ~40m above the Gihon Spring, more than halfway to the top of the donkey trail. At that height, out of harms way carriers would exit a narrow tunnel and carry water the rest of the way into the city.
A natural cave, dated to paleolithic and chalcolithic periods was the original entrance to natural caustic WSS formation. The cave (pictured below), just west of Building 2482 was eventually sealed with a wall, most likely when W108 and 109 were constructed to further secure access to the expanded WSS. The floor of the cave eventually collapsed. Interestingly a recent finding
confirmed a massive earthquake late in the Iron Age, which may have been the cause of the floor collapse.
The elevated city provided defensive advantage, especially for prolonged sieges that typically surrounded a city or attacked the water and produce supply line to starve its population and flush them out. For Bronze Age Jerusalem that supply line was at or around the Gihon Spring, the route up the eastern escarpment and the exposed entry to the city from the north. Any enemy force that could prevent food supply would essentially starve the city except for the life-line of water via WSS.
The remnant of the recently discovered late Iron Age wall, built by Hezekiah to stave off the Assyrian threat was constructed on a line that entirely ran over the RCR's. Archaeologists validated this 200 meters stretch of wall, on the eastern escarpment as Jerusalem's only defensive city wall, none has been discovered on the west.
Under the wall, on the RCR bedrock of room 2 (see RCR image above) a matzevah (discovered by Eli Shukron 2009) had been entirely preserved in soft sand by the constructors of the wall. The matzevah is the modern City of David's largest, in-situ, intact artifact that has survived earthquake and destruction, because the wall surrounded and protected it. This is strong indication that the King, who constructed the wall, most likely Hezekiah ordered preservation of the matzevah because it reflected his compatible belief in line with that of Azariah, the High Priest and Isaiah, the prophet of the nation at that time.

None of the indications in the RCR bedrock inform of its earliest use. However, if this temple complex was indeed used by priests who practiced what would become Jewish custom, then the matzevah is problematic because the Jewish Bible prohibited such use. This can be seen in the words of Deuteronomy 16 below:
21 לֹֽא־תִטַּ֥ע לְךָ֛ אֲשֵׁרָ֖ה כׇּל־עֵ֑ץ אֵ֗צֶל מִזְבַּ֛ח יְהֹוָ֥ה אֱלֹהֶ֖יךָ אֲשֶׁ֥ר תַּעֲשֶׂה־לָּֽךְ׃
You shall not set up a sacred post—any kind of pole beside the altar of the LORD your God that you may make—
22 וְלֹֽא־תָקִ֥ים לְךָ֖ מַצֵּבָ֑ה אֲשֶׁ֥ר שָׂנֵ֖א יְהֹוָ֥ה אֱלֹהֶֽיךָ׃
or erect a stone pillar (matzevah); for such the LORD your God detests.
However, in an apparent contradiction (Genesis 28:18-22), some 270 years before Biblical laws were collectively accepted by the Israelite nation, Jacob erected and anointed a matzevah to mark his covenant. Naturally the question must be asked; whether a matzevah at this compatibly Jewish, cultic RCR temple complex should indicate an early use based solely on this Biblical prohibition from the end of the Middle Bronze Age?
The original path from water to RCR's was discovered and mapped by Parker-Vincent, but the east end of passage XVIII (see below) had been quarried, disconnecting it from or to the lower section of bedrock. Topology of in-tact bedrock, north and south suggests XVIII would have sloped similarly. Thus, we can conclude that before the Rock-Cut-Feature (RCF) was quarried and emptied, its once untouched bedrock provided uninterrupted egress to and from the Gihon Spring or steps to the
Round Chamber and Channel II filled it to a maximum depth of around 1m.

The Bronze Age consensus for W108-W109 construction and presumption that the RCF was the quarry for these massive walls suggests RCF was in-tact until at least these constructions. Therefore, when passage XVIII collapsed or was cut, at its eastern end temple worship on or at the RCR's ceased because once W108-W109 and Wall 3 were constructed access along passage XIX was also blocked. The combination of these terminated passages sealed the fate for any practical future use of RCR's as a temple for worship.
Archaeological evidence suggests the Bronze Age population averaged no more than 800 people, and Late Bronze Age Jerusalem appears to be even smaller. At a maximum the population would have been around 1250 people living on the ridge of Mount Moriah. It's hard to imagine, given the massive scale of these complex constructions that such a small population could have independently supported these undertakings. Further, limited Late Bronze Age evidence suggests the population diminished, perhaps after initial construction was completed.
The most intriguing and complete evidence from the Late Bronze Age,
found in the Amarna letters suggests Egypt's hand in the affairs of 'Urusalim', which prompted Steiner to write in 2003 (abridged):
“Realizing that Urusalim from the Amarna letters must be associated with Jerusalem, I began to read carefully and discovered another possibility that might account for the lack of archaeological evidence from the fourteenth century. There is no reference to the city itself, nor to its walls or its strong gates. Maybe Urusalim was not a city or large town at all. Maybe we should interpret the “lands of Urusalim” as a royal dominion of the pharaoh, with Abdi-heba as his steward, who lived in a fortified house somewhere near the spring.”
Perhaps we are left to imagine that Canaanite or Jebusite anxiety, after Israel departed Egypt prompted pharaoh to transform the landscape of the Gihon spring. W108-109 divided the eastern slope, secured entry to WSS and with Wall 3 cut access via XIX to RCR's. To add insult the pharaoh cut the ancient access passage via XVIII and the RCF left a gaping, impassable hole in the bedrock.
The layered time context of the archaeological evidence paints a picture of cave dwellers, early farmers, community, cultic practice, organized supply, defensive activity, and centralized authority. Leading to the end of the Middle Bronze Age's sophisticated construction, bedrock transformation and population expansion. Then, in the Late Bronze Age population downsizing, limited advancement and vassal acknowledgement until the arrival of the Iron Age when renovation, expansion and development into the City of David recommence with vigor.
If Israel had become Egypt's spiritual nemesis, transformation of the Gihon Spring had the desired effect. After returning from their 250 year exile in Egypt Israel were kept out of Jerusalem for more than 300 years, until the Iron Age. By then the RCR temple was most likely buried and unknown to the mountain residents and certainly to the generations of Israelites. By the time King David conquered the tower of Zion, the spring citadel and captured the defensive water supply tzinor or "pipe" (WSS) the RCR temple was long forgotten. Perhaps The constructor's of Hezekiah's terminal Iron Age wall were the first, in more than 1000 years to reveal the ancient bedrock RCR temple that pre-dated the Jewish religion on the eastern face of Mount Moriah.
