The rather specific and detail-oriented measurements and emotional enthusiasm over the completion of the tunnel also embody the knowledge base of an engineer’s expertise with regards to trying to establish the author of the text. Eventually weighing the possibility of an engineer in Judah writing the inscription himself or hiring a scribe unaffiliated with the monarchy, Davies contends, “Therefore, I propose that the engineer(s) of the Shiloah Tunnel project hired a professional scribe to write an inscription.” While an analysis of the paleography of the Siloam Inscription suggests that it was written under the command of a chief engineer and not King Hezekiah, radiometric dating, the biblical account, and archeological evidence of the buildup of defenses encompassing the reign of Hezekiah, all verify the same explanation that King Hezekiah may not have ordered the scribing of the Siloam Inscription, but he did indeed demand the digging of the Siloam Tunnel which housed the inscription. Ascending the throne as king of Judah in 716 BCE, Hezekiah’s initial policies and reforms established various strategies, programs, and improvements to deter and defend Judah from a likely Assyrian offensive that would eventually come to fruition circa 701 BCE.
The tunnel, which is about 500 meters (550 yards) long, brings water from the Gihon Springs, located some 300 meters (330 yards) outside the walls of old Jerusalem, to the Siloan Pool inside the ancient city.It was built to protect the city's water supply during an Assyrian siege.In contrast to that, the previous water system did release all the water not used by the city population into the Kidron Valley to the east, where besieging troops could have taken advantage of it.The curving tunnel is 533 m long, and by using the 30 cm altitude difference between its two ends, which corresponds to a 0.06 percent gradient, the engineers managed to convey the water from the spring to the pool.Researchers using sophisticated radio-dating techniques have concluded that a tunnel running under ancient Jerusalem was indeed constructed around 700 B.
C., during the reign of King Hezekiah, just as it is described in the Bible., Nikbat Ha Shiloah), also known as Hezekiah's Tunnel, is a water tunnel that was carved underneath the City of David in Jerusalem in ancient times.Its popular name is due to the most common hypothesis of its origin, namely that it dates from the reign of Hezekiah of Judah (late 8th and early 7th century BCE) and corresponds to the Water Works mentioned in 2 Kings in the Bible.Structures described in the Bible are notoriously difficult to date.While some are poorly preserved or hard to identify, others are off limits to scientists because of political reasons.According to the Bible, King Hezekiah prepared Jerusalem for an impending siege by the Assyrians, by "blocking the source of the waters of the upper Gihon, and leading them straight down on the west to the City of David" (2 Chronicles 32).
