Hezekiah, king of Judah, rebelled against Assyria, and Jerusalem survived King Sennacherib's 701 BC siege when other cities fell.
See it on the Bible & Christianity map →What it is
2 Kings 18–20 and Isaiah 36–39 tell how Hezekiah removes idols and shrines, then stops paying Assyria tribute. Sennacherib destroys Judah's fortified towns and besieges Jerusalem, his envoy taunting its defenders. Hezekiah prays, Isaiah promises deliverance, and 'the angel of the Lord' strikes 185,000 Assyrians overnight (2 Kings 19:35). Sennacherib goes home. To prepare, Hezekiah had cut a 533 m water tunnel under the city.
Why it matters
Jerusalem's escape seemed to prove God would protect Zion, a belief that made Babylon's conquest a century later an even deeper shock.
Life, legacy and sources
Unusually rich: Sennacherib's prism boasts he shut Hezekiah up 'like a bird in a cage' and took 46 towns; his palace reliefs show the siege of Lachish. Hezekiah's tunnel, its Siloam inscription and an impression of his royal seal survive.
Questions and debates
Why Sennacherib withdrew without taking Jerusalem is unknown: plague, trouble at home, an Egyptian army, or Hezekiah's heavy tribute.

▸King Hezekiah and Sennacherib's siege ruled Judah just after Assyria conquers Israel (fall of Samaria)Historical record
The connection
Samaria's fall put Assyria on Judah's doorstep and sent refugees south, and Jerusalem swelled several times over. 2 Chronicles 30 says Hezekiah invited the north's survivors to Passover in Jerusalem; his purge of rural shrines also cast Judah as the heir of all Israel.
When and where
Jerusalem, late 8th century BC; Hezekiah came to the throne around 715 BC, less than a decade after 722 BC.
Historical evidence
Excavations show Jerusalem grew roughly three- to fivefold then; Hezekiah's 'Broad Wall', about 7 m thick, enclosed the new western quarter.
Questions and debates
His accession date is disputed: 2 Kings 18:10 puts Samaria's fall in his sixth year, implying he already reigned in 722 BC.
▸King Hezekiah and Sennacherib's siege was advised by Isaiah the prophet and the Book of IsaiahMostly agreed by scholars
The connection
As Sennacherib's envoy demanded surrender, Hezekiah sent officials to Isaiah, who answered that the Assyrian king 'shall not come into this city' (2 Kings 19:32). Isaiah also opposed relying on Egypt, and when Hezekiah fell ill, promised him fifteen more years (2 Kings 20).
When and where
Jerusalem, during the 701 BC Assyrian invasion; told in both 2 Kings 18–20 and Isaiah 36–39, nearly word for word.
How do we know?
Assyrian records confirm the siege. Ophel excavations in Jerusalem turned up Hezekiah's seal impression and one possibly reading 'Isaiah, prophet' about 3 m apart (published 2015 and 2018).
Questions and debates
The second seal is damaged and missing a final letter, so 'prophet' is uncertain. Whether Isaiah's promises were written before or after 701 BC is debated.
