Sennacherib, king of Assyria, attacked and captured all the fortified cities of Judah in the 14th year of King Hezekiah's reign. Sennacherib then prepared to lay siege to Jerusalem itself, but Hezekiah strengthened Jerusalem's defenses. Sennacherib initially agreed to peace terms with Hezekiah but ultimately broke the agreement and sent his army to besiege Jerusalem. The document provides historical context and commentary on this biblical account.
