Commentary on Isaiah 36

Isaiah 36 marks a dramatic pivot from prophecy to narrative. The Assyrian king Sennacherib has conquered every fortified city of Judah, and now his field commander stands outside Jerusalem’s walls, taunting the people in Hebrew. He mocks their trust in Egypt, their military weakness, and — most pointedly — their confidence in the Lord. The chapter sets up the central crisis of the book’s second half: will Jerusalem trust God or collapse under the weight of Assyrian intimidation? The narrative is spare, almost clinical, but the theological stakes could not be higher. This is not merely a political siege; it is a trial of faith.

Historical context

The year is 701 BC. Assyria, under Sennacherib, is the dominant empire in the ancient Near East. The northern kingdom of Israel has already fallen (722 BC), and Judah survives only as a vassal state. King Hezekiah, who has attempted religious reform and trusted in the Lord, also made the fatal political mistake of joining an anti-Assyrian coalition with Egypt — a “broken reed of a staff” (Isa 36:6).

The Assyrian field commander (the Rabshakeh, a title, not a name) speaks fluent Hebrew and knows Judahite theology well enough to twist it. His speech is a masterpiece of psychological warfare: he offers a “blessing” from Sennacherib, promises a land of plenty, and claims the Lord himself sent Assyria to destroy Judah. The chapter is almost verbatim parallel to 2 Kings 18:17-37, suggesting a common source — likely an official court record. The setting is the conduit of the upper pool, the same location where Isaiah confronted Ahaz with the sign of Immanuel (Isa 7:3). The contrast is deliberate: Ahaz refused to trust; Hezekiah will be tested.

Verse by verse

• 1:

  In the fourteenth year of King Hezekiah, Sennacherib king of Assyria came up against all the fortified cities of Judah and took them. The narrative opens with total military collapse. Every walled city in Judah — Lachish, Azekah, the rest — has fallen. Only Jerusalem remains. The verse sets the stage for a crisis that is both political and theological: if God’s covenant promises are tied to David’s throne, what happens when the empire is at the gate?

• 2:

  The king of Assyria sent the Rabshakeh from Lachish to Jerusalem. Lachish was Sennacherib’s command post; its siege is famously depicted in Assyrian reliefs now in the British Museum. The Rabshakeh arrives with a great army, but his weapon is words. He stations himself at the conduit of the upper pool — the same spot where Isaiah told Ahaz to ask a sign (Isa 7:3). The geography is a silent sermon: the place of unbelief becomes the place of testing.

• 4:

  The Rabshakeh begins: “Say to Hezekiah, Thus says the great king, the king of Assyria: On what do you rest this trust of yours?” The question is the theological heart of the chapter. The Hebrew word for “trust” (bitakhon) appears repeatedly. The Assyrian’s challenge is not just military; it is a direct assault on the object of Judah’s faith. He demands an answer: in whom do you trust?

• 5:

  “Do you think that mere words are strategy and power for war?” The Rabshakeh mocks Hezekiah’s reliance on diplomatic talk. But the irony cuts both ways: the Assyrian himself is using words as his primary weapon. The verse exposes the fragility of human confidence — whether in armies, alliances, or rhetoric.

• 6:

  “Behold, you are trusting in Egypt, that broken reed of a staff.” The image is vivid and humiliating. A reed that splinters when leaned on, piercing the hand. Egypt was notoriously unreliable as an ally (see Isa 30:1-7). The Rabshakeh knows Judah’s foreign policy better than Judah’s leaders seem to. His accusation is historically accurate — and theologically devastating, because trusting Egypt meant distrusting the Lord.

• 7:

  “But if you say to me, ‘We trust in the Lord our God,’ is it not he whose high places and altars Hezekiah has removed?” Here the Rabshakeh shows his theological sophistication. He knows that Hezekiah centralized worship in Jerusalem, tearing down the high places (2 Kgs 18:4). He twists this reform into an act of impiety: you’ve offended God by destroying his altars, so why would he help you? It is a diabolical misreading — but it sounds plausible to the people on the wall.

• 8:

  “Come now, make a wager with my master the king of Assyria: I will give you two thousand horses, if you are able on your part to set riders on them.” The taunt is layered. First, it is a boast of Assyrian wealth. Second, it exposes Judah’s military weakness — they lack even enough cavalry. Third, it is a psychological trap: if you can’t accept this challenge, how can you resist the full Assyrian army? The Rabshakeh is not negotiating; he is crushing morale.

• 10:

  “Moreover, is it without the Lord that I have come up against this land to destroy it? The Lord said to me, Go up against this land and destroy it.” This is the most dangerous claim of all. The Rabshakeh co-opts the language of divine commission. He knows that Isaiah has prophesied Assyria as the rod of God’s anger (Isa 10:5). He twists that truth into a lie: God is not using Assyria to discipline Judah; Assyria is claiming God’s endorsement for total destruction. The people on the wall must distinguish between God’s sovereign purposes and the enemy’s blasphemous spin.

• 11:

  Eliakim, Shebna, and Joah say to the Rabshakeh, “Please speak to your servants in Aramaic, for we understand it. Do not speak to us in the language of Judah within the hearing of the people who are on the wall.” The request is a desperate attempt to contain the damage. Aramaic was the diplomatic language of the empire; Hebrew was the language of the common people. The officials want to shield the populace from the psychological assault. But the Rabshakeh refuses — his target is precisely the people’s faith.

• 16:

  “Do not listen to Hezekiah. For thus says the king of Assyria: Make your peace with me and come out to me. Then each one of you will eat of his own vine and fig tree, and drink water of his own cistern.” The offer is seductive: surrender and enjoy a peaceful, prosperous life. The vine and fig tree are classic images of covenant blessing (1 Kgs 4:25, Mic 4:4). The Rabshakeh promises what God promised — but on Assyria’s terms. It is the temptation of a shortcut to shalom, a false gospel of submission to the empire.

• 18:

  “Beware lest Hezekiah mislead you by saying, ‘The Lord will deliver us.’ Has any of the gods of the nations ever delivered his land out of the hand of the king of Assyria?” The Rabshakeh appeals to history. Every nation that resisted Assyria fell. Their gods could not save them. Why would Judah’s God be different? The argument is powerful because it is empirically true — from a purely human perspective. The chapter forces the reader to ask: is the Lord like the gods of the nations, or is he different?

• 21:

  But the people were silent and answered him not a word, for the king’s command was, “Do not answer him.” Silence is the only appropriate response to blasphemy that cannot be reasoned with. Hezekiah’s instruction is wise: do not engage in debate with someone who has already rejected the premise of faith. The silence is not weakness; it is a refusal to let the enemy set the terms of the conversation.

• 22:

  Then Eliakim, Shebna, and Joah came to Hezekiah with their clothes torn, and told him the words of the Rabshakeh. The torn clothes are a sign of mourning and horror. The officials do not try to spin the news or offer a plan. They simply report what was said — and leave the king to do what kings do: lead. The chapter ends with the crisis fully exposed, the question hanging in the air: what will Hezekiah do?

Application

This chapter is a masterclass in spiritual warfare — not the kind with swords and chariots, but the kind that happens in the mind and heart. The Rabshakeh’s tactics are still used today: mockery of faith, appeals to worldly power, twisted theology, and promises of an easier path. When the world tells you that trusting God is naive, that history is against you, that compromise is the only way to peace — the chapter calls you to recognize the voice for what it is.

Notice what Hezekiah’s officials do not do. They do not argue. They do not panic. They do not try to negotiate. They go to the king and report. In the Christian life, that means taking the assault to Christ in prayer. The silence of the people on the wall is not passivity; it is a refusal to let the enemy dictate the terms of the battle. When the lies come, sometimes the most faithful response is to say nothing to the accuser and everything to the Lord.
