Bible Fact · 2 Kings 20:20 — 'Hezekiah... made the pool and the conduit and brought water into the city.'
Hezekiah's Tunnel
The Fact
Beneath the City of David in Jerusalem runs a remarkable tunnel carved through solid bedrock. It stretches 533 meters (about 1,750 feet) and channels water from the Gihon Spring to the Pool of Siloam. The tunnel was commissioned by King Hezekiah around 701 BC when Assyrian king Sennacherib threatened to besiege Jerusalem. By redirecting the city's water supply underground, Hezekiah denied the enemy access to water while ensuring the city's survival (2 Kings 20:20; 2 Chronicles 32:30). What makes the tunnel extraordinary is that two teams dug from opposite ends simultaneously and met in the middle — an incredible feat of ancient engineering. Inside the tunnel, an inscription called the Siloam Inscription (discovered in 1880) describes the workers' voices guiding each other as they dug toward the sound. Today visitors can wade through the tunnel in knee-deep water. The tunnel still flows and remains one of the best-preserved ancient structures in Jerusalem.
Context
The Siloam Inscription found inside describes workers hearing each other's pickaxes and steering toward the sound — a vivid first-person account of one of history's great engineering projects.
Significance
Hezekiah's Tunnel is a tangible monument to the biblical account of his preparations for Sennacherib's siege, exactly as described in 2 Kings and 2 Chronicles.
Reflection
Hezekiah prepared practically while also praying and trusting God. What does wise preparation that still relies on God look like in your own life?
