In preparation for Sennacherib's invasion into Judah in 701 BCE, King Hezekiah undertook a massive engineering project. Access to the Gihon Spring, Jerusalem's principal water source, was only possible by leaving the fortifications. Thus Hezekiah ordered that a tunnel 1750 feet (530 m) in length be cut to bring the water inside the city's walls. Two teams dug from both sides hoping to meet in the middle. This amazing event was accomplished, and it was commemorated both in the Bible (2 Kgs 20:20; 2 Chr 32:30) and in an inscription carved inside the tunnel near the Siloam Pool. A boy found the inscription while bathing in the tunnel in 1880, and it was studied by the explorer Conrad Schick. The Siloam Inscription was cut out in 1890, and it currently resides in the Museum of the Ancient Orient in Istanbul Turkey.
Dude! Wanna read a translation of the Siloam Inscription?
