Late 8th-century BC monumental Paleo-Hebrew inscription recording the excavation of Hezekiah's water tunnel
A six-line Paleo-Hebrew inscription carved into the rock wall near the southern exit of the 533-meter subterranean conduit diverting water from the Gihon Spring to the Pool of Siloam.
Rigorous 4-part empirical analysis separating ancient text from bias and consensus
The text describes the dramatic climax of the engineering feat: while stonecutters swung their axes toward each other, an echo was heard, and on the day of the breakthrough, the miners struck axe against axe and water flowed 1,200 cubits to the reservoir.
Corroborates 2 Kings 20:20 ('he made the pool and the conduit and brought water into the city') and 2 Chronicles 32:30 ('Hezekiah closed the upper outlet of the waters of Gihon and directed them down to the west side of the City of David').
Epigraphically dated to the late 8th century BC by Frank Moore Cross and Nahman Avigad; a 1996 proposal by Rogerson & Davies for a Hasmonean date was refuted by radiometric dating of underlying plaster by Frumkin et al. (2003).
Remarkably absent of royal self-aggrandizement: the inscription celebrates the anonymous quarrymen and laborers rather than attributing the glory directly to King Hezekiah.
