Seldom does a "terminus post quem", the earliest date an item came into existence, and a "terminus ante quem", the latest, perfectly sandwich an artifact to define its absolute archaeological age.
In ancient Jerusalem, on Mount Moriah's eastern slope, a crucial study by Weizmann Institute, Tel Aviv University and Israel Antiquities Authority dated evidence in a water channel, beneath and above a plaster layer that was built on top of clay-rich, virgin soil in a natural bedrock cavity.
Directly beneath the plaster (its earliest date), small charcoal flecks were dated separately (sample 9965 and 10293) between 1615–1545 BCE, a "terminus post-quem" for plaster in the channel. At the end of the channel, above the plaster (the latest date) several grey and white laminations were found with charred material (sample 9964 and 10292), "ante-quem", understood to represent the channel was last used between 1535 and 1445 BCE.
The water channel was only ever used, during these maximum 80 to 100 years, to propel water (by gravity) onto the bedrock floor of at least one of two rooms (1 and 3) of the Temple Zero complex immediately below (east of) Area U. The water channel was not used previously nor has it been used since. Slaughtered animals would have frequently been processed and offered as a sacrifice, thus requiring water be flushed via the channel to clean blood and excrement. Almost 600 years later similar hydraulic systems were engineered and used in the first and second temples further up the mountain.

In the Biblical context of Area U, the rock-cut-rooms of Temple Zero and the Gihon Spring, Bible commentators relate events of Adam, Noah, Shem or Malchi-Tzedek, Abraham, Isaac, Jacob, Joshua, King David and subsequent kings. Spanning thousands of years, the area on Mount Moriah is also referred by many names including; Salem, Beit El, Yireh (Yireh-Salem), Luz, Tzion, Jebus, City of David and Jerusalem.

By aligning the city of Ai and Biblical events with the 100 year overlapping use of the drainage channel, confidence rises that Temple Zero is the location Jacob erected the recently discovered matzevah on which he made a covenant, to which he returned and accepted upon himself the name "Israel".
For the modern nation to rediscover the original beacon, erected by Jacob on which he accepted the name of their national identity would be nothing short of miraculous, perhaps too much for the archaeological fraternity to acknowledge.
