Isaiah 36:15—Core Text

“Do not let Hezekiah persuade you to trust in the LORD, saying, ‘The LORD will surely deliver us; this city will not be delivered into the hand of the king of Assyria.’” (Isaiah 36:15)


Geopolitical Landscape

During the late eighth century BC the Neo-Assyrian Empire dominated the Near East. Under Tiglath-Pileser III, Shalmaneser V, Sargon II, and finally Sennacherib, Assyria perfected a system of rapid military campaigns, deportations, and vassalage. By the time Sennacherib mounted his western campaign (traditionally 701 BC; Ussher chronology c. 712 BC), every kingdom between Nineveh and the Nile had felt Assyrian pressure.


Judah under King Hezekiah

Hezekiah (reigned c. 715–686 BC conventional; c. 726–698 BC Ussher) inherited a vassal Judah burdened by previous Assyrian tribute (2 Kings 18:14). His sweeping religious reforms destroyed high places, smashed the bronze serpent, restored Temple worship, and celebrated a grand Passover (2 Chronicles 29–31). The chronicler records, “He trusted in the LORD, the God of Israel” (2 Kings 18:5), setting the spiritual backdrop for Assyria’s challenge.


Assyrian Campaign of the Fourteenth Year

Isa 36:1 fixed the timing: “In the fourteenth year of King Hezekiah, Sennacherib king of Assyria attacked all the fortified cities of Judah and captured them” . Sennacherib’s annals—preserved on the Taylor Prism (British Museum no. BM 91 032)—boast of besieging 46 walled towns, deporting 200,150 people, and shutting Hezekiah “like a caged bird” in Jerusalem.


The Siege Corridor: Lachish to Jerusalem

After crushing Lachish (reliefs discovered in Sennacherib’s palace at Nineveh, now in the British Museum), Assyrian forces advanced to Jerusalem. Archaeological layers at Lachish (Level III) show conflagration consistent with an Assyrian assault. Hezekiah fortified Jerusalem’s walls, built a broad wall (still visible in the Jewish Quarter), and excavated the 533-meter Siloam Tunnel to secure water; the tunnel’s Siloam Inscription (KAI 189) records the engineering feat.


Rabshakeh’s Psychological Warfare

Assyria’s field commander (the “Rab-shakeh”) delivered a trilingual propaganda speech at the Gutter’s Field. His tactic: undermine confidence in Yahweh, ridicule Hezekiah’s reforms, and discredit any alliance with Egypt (Isaiah 36:4–10, 18–20). Verse 15 captures his central taunt: your God will not rescue you.


International Alliances

Isaiah had long warned Judah against relying on Egypt (Isaiah 30:1–5; 31:1). Egyptian forces under Taharqa (Isaiah 37:9) briefly pushed northward, but Isaiah’s prophecy held: salvation would come not from horses and chariots but from the Lord of Hosts.


Chronology Synchronism

• Conventional chronology: Hezekiah’s fourteenth year = 701 BC.

• Ussher’s chronology: 726 BC accession; fourteenth year ≈ 712 BC.

Either reckoning places the event two decades before Jerusalem’s fall to Babylon (586 BC).


Archaeological Corroborations

• Taylor Prism: mentions exact tribute—30 talents of gold, 800 talents of silver—matching 2 Kings 18:14–16.

• Bullae: a 2015 excavation in the Ophel revealed Hezekiah’s seal impression, inscribed “Belonging to Hezekiah, son of Ahaz, king of Judah.”

• Lachish reliefs: depict Assyrian siege ramps, battering rams, and Judean captives.

• Siloam Tunnel & inscription: verify Hezekiah’s water-defense preparations (2 Chronicles 32:30).

• Also noteworthy: Herodotus 2.141 alludes to an Assyrian defeat near Pelusium, possibly echoing the same plague.


Miraculous Deliverance

Isa 37:36 records, “Then the angel of the LORD went out and struck down 185,000 in the camp of the Assyrians” . Sennacherib retreated to Nineveh, conspicuously omitting Jerusalem’s capture from his inscriptions—a silent admission of failure. Josephus (Ant. 10.1.5) describes a plague; Greek historian Herodotus, mice gnawing quivers (symbolic of pestilence). Scripture attributes the victory solely to divine intervention.


Theological Emphasis

Isaiah drives a covenantal lesson: trust in Yahweh is not misplaced (cf. Isaiah 26:3–4). Hezekiah’s reliance contrasts with Rabshakeh’s mockery. The event foreshadows the ultimate deliverance through Christ, “Immanuel—God with us” (Isaiah 7:14; Matthew 1:23), whose resurrection permanently overthrows every worldly power (Romans 1:4; Ephesians 1:20–22).


Summary

Isaiah 36:15 stands amid the 701 BC Assyrian crisis when Sennacherib’s armies surrounded Jerusalem. Hezekiah’s reforms, Assyrian imperialism, Egypt’s faltering aid, and prophetic exhortation converge. Archaeological inscriptions, Assyrian records, and the Dead Sea Scrolls corroborate the narrative. God’s miraculous deliverance authenticates His sovereignty, prefigures the salvation accomplished in Christ, and calls every generation to trust in the LORD alone.
