Message: Dire situation ("children to birth, no strength"); pray against Rabshakeh's (Assyrian official) blasphemies for remnant.
Isaiah's reply: God heard blasphemies; do not fear; God will send rumor, cause Sennacherib to retreat and die by sword.
Rabshakeh leaves for Libnah (hears of Ethiopian King Tirhakah advancing); sends letter taunting Judah's God, listing conquered nations (Gozan, Haran, etc.).
Hezekiah spreads letter before Lord, prays: Acknowledges God's uniqueness, other gods false; save to prove You alone are God.
God's Response via Isaiah
God heard prayer; mocks Sennacherib (Zion despises him).
Rebukes Assyrian pride (chariots, conquests); God orchestrated their victories to destroy idols.
Judgment: Hook in nose, send back; sign for Judah—eat self-grown produce years 1-2, full harvest year 3; remnant preserved from Jerusalem.
Assyrians won't enter city; God defends for His name and David's sake.
Angel kills 185,000 Assyrians overnight; Sennacherib retreats to Nineveh, killed by sons Adrammelech and Sharezer while worshiping Nisroch; they flee to Ararat; Esarhaddon reigns.
