In 705 ʙ.ᴄ., King Hezekiah of Judah stopped paying tribute to Assyria, and began to fortify Jerusalem in preparation for an Assyrian siege. His fortifications included building a ½-kilometer tunnel under the city wall to bring water from the Gihon Spring into the city. In 2010 BYU-Jerusalem religion professor Bill Hamblin walked the entire tunnel with his students and a video camera.
