of his predecessors (cf. 2 Chronicles 33–34 and 2 Kings 21–23). In the days of King Hezekiah King Hezekiah is the last biblical figure mentioned as having seen the Ark. Hezekiah is also known for protecting Jerusalem against the Assyrian Empire by improving the city walls and diverting the waters of the Gihon Spring through a tunnel known today as Hezekiah's Tunnel, which channeled the water inside the city walls to the Pool of Siloam. In a noncanonical text known as the Treatise of the Vessels, Hezekiah is identified as one of the kings who had the Ark and the other treasures of Solomon's Temple hidden during a time of crisis. This text lists the following hiding places, which it says were recorded on a bronze tablet: (1) a spring named Kohel or Kahal with pure water in a valley with a stopped-up gate; (2) a spring named Kotel (or "wall" in Hebrew); (3) a spring named Zedekiah; (4) an unidentified cistern; (5) Mount Carmel; and (6) locations in Babylon. To many scholars, Hezekiah is also credited as having written all or some of the Book of Kohelet (Ecclesiastes in the Christian tradition), in particular the famously enigmatic epilogue. Notably, the epilogue appears to refer to the Ark story with references to almond blossoms (i.e., Aaron's rod), locusts, silver, and gold. The epilogue then cryptically refers to a pitcher broken at a fountain and a wheel broken at a cistern. Although scholars disagree on whether the Pool of Siloam's pure spring waters were used by pilgrims for ritual purification, many scholars agree that a stepped pilgrimage road between the pool and the Temple had been built in the first century CE. This roadway has been partially excavated, but the west side of the Pool of Siloam remains unexcavated. The Babylonian conquest and aftermath In 587 BC, the Babylonians destroyed Jerusalem and Solomon's Temple. There is no record of what became of the Ark in the Books of Kings and Chronicles. An ancient Greek version of the biblical third Book of Ezra, 1 Esdras, suggests that Babylonians took away the vessels of the ark of God, but does not mention taking away the Ark: In Rabbinic literature, the final disposition of the Ark is disputed. Some rabbis hold that it must have been carried off to Babylon, while others hold that it must have been hidden lest it be carried off
