Lesson 1 · Isaiah 36–39
Hezekiah’s Tests and Deliverance
The final chapters of Hezekiah’s life: the strategies Assyria used against Judah, Hezekiah’s moments of strength and weakness through the siege, his healing and the envoys from Babylon, and the warnings Isaiah delivered — warnings more relevant to us today than we might expect.
For the teacher
Lesson plan
- Aim
- That the class draw practical lessons from the close of Hezekiah’s life: recognize the tactics used to erode trust in God and in godly leaders, see both the strength of turning to the Lord and the danger of pride and short-sightedness, and take to heart Isaiah’s warnings about legacy and future generations.
- Bring
- Bibles; a printed copy of the questions (the Questions only view) for each person. For a fuller picture of Hezekiah’s life, encourage everyone to read 2 Kings 18–20 and 2 Chronicles 29–32 alongside Isaiah 36–39.
- Open
- Tell the class these chapters contain a lot of material, so some sections will be summarized and others skipped. Set the scene: the late 8th century BC, somewhere between 715 and 686 BC; Israel already conquered by Assyria around 722 BC; and now Sennacherib, king of Assyria, against Judah. Then state the focus: the strategies of Hezekiah’s enemies, his moments of strength and weakness, and the warnings Isaiah delivered.
- Close
- Walk through the Lessons for Today: our walk in faith should not be a solo journey (Psalm 78:5–7; Deuteronomy 6:6–7); prayerful intercession for others is a sign of strength, not weakness (Isaiah 36–37); focus on today’s challenges, aware that a tomorrow may come (Psalm 90:12; James 4:14); and our legacy is not defined by what we accumulate (3 John 1:4). Close by asking how Hezekiah’s faith both shone and faltered across these chapters.

The Assyrian Strategy
Teaching note
Rabshakeh is pronounced RAB-shuh-keh; Sennacherib, seh-NACK-er-ib. Set the Assyrian tactics beside Satan’s strategy one for one, and let the class name where each shows up today. Isaiah 10:5 and Isaiah 30–31 are the background references for the setting.These events come late in the 8th century BC, in the reign of Hezekiah (somewhere between 715 and 686 BC). The northern kingdom of Israel has already been conquered (around 722 BC), and now Sennacherib, king of Assyria, has come up against all the fortified cities of Judah and taken them (36:1). God had selected Assyria to be “the rod of mine anger” (Isaiah 10:5), and Judah had been warned not to rely on outside alliances (Isaiah 30–31).
Sennacherib sends the Rabshakeh to Jerusalem with a great army, and his speech is a deliberate strategy. He undermines trust in Hezekiah: “What confidence is this wherein thou trustest?” (verses 4–6). He mocks their faith, turning Hezekiah’s removal of the high places and altars into an offense against the Lord (verse 7). He boasts in Assyria’s strength, offering two thousand horses if Judah can even find riders for them (verses 8–9). He tries to redirect God’s blessing to Assyria: “Jehovah said unto me, Go up against this land, and destroy it” (verse 10).
Then he speaks past the officials to the people on the wall. He provides false hope — make peace, come out, and eat every one of his own vine and fig tree, until he takes them away “to a land like your own land” (verses 16–17). And he attacks their faith directly: the gods of Hamath, Arpad and Sepharvaim did not deliver their lands, so why should the Lord deliver Jerusalem (verses 18–20)?
These are Satan’s strategies as well. He discredits godly leadership, twists truth into falsehood, promotes trust in power rather than in God, misuses God’s word to justify ungodly actions, provides appeals to emotional responses, and relativizes God, belittling His significance, power and authority.
-
Question 1. What tactics did the Assyrians use to erode the people’s trust in both Hezekiah and God? How do similar strategies work in our world today?
Suggested answer
The Rabshakeh used intimidation, mockery and misinformation. He undermined trust in Hezekiah’s leadership (“Let not Hezekiah deceive you”) and in God’s power to save, comparing the Lord to the failed gods of other nations, and he appealed to reason and fear, offering security in exchange for surrender. Today similar tactics appear in secular ideologies, media and peer influence that mock faith, question God’s reliability, and promise comfort in compromise.
-
Question 2. The Rabshakeh claimed, “Jehovah said unto me, Go up against this land, and destroy it” (36:10). Was there any truth in this?
Suggested answer
There was a grain of truth: God had selected Assyria as “the rod of mine anger” against His people (Isaiah 10:5). But the Rabshakeh twisted it into a lie, for the Lord had not given Jerusalem into his hand, and He turned Assyria back the way it came (37:33–35).

Hezekiah’s Response
Teaching note
In the Lesson 13 review this point is framed as a contrast between Hezekiah’s response in the setting of Isaiah 31 (leaning on alliances and paying tribute) and his response in chapter 37. Read 2 Kings 18:14–16 aloud to make the contrast plain.Hezekiah immediately seeks out the Lord. He tears his clothes, covers himself with sackcloth, and goes into the house of the Lord (37:1). He acknowledges his need — “the children are come to the birth, and there is not strength to bring forth” — and sends to Isaiah, asking him to “lift up thy prayer for the remnant that is left” (verses 3–4). And he accepts God’s word through the prophet: “Be not afraid of the words that thou hast heard” (verses 6–7).
When Sennacherib sends a letter repeating his threats, Hezekiah spreads it before the Lord and prays earnestly (verses 14–20). He confesses that the Lord alone is God of all the kingdoms of the earth, and asks Him to save them “that all the kingdoms of the earth may know that thou art Jehovah, even thou only.”
This is a far better reaction than bribery and trusting man. When Sennacherib first came against Judah’s cities, Hezekiah sent word, “I have offended; return from me,” and paid the tribute with the silver of the house of the Lord and the gold stripped from the temple doors (2 Kings 18:14–16) — the very reliance on man that Isaiah had warned against (Isaiah 31). Reliance on God is not weakness: “My grace is sufficient for thee: for my power is made perfect in weakness” (2 Corinthians 12:9–10).
-
Question 3. How does Hezekiah’s initial response to the Assyrian threat contrast with his later response to the threat of death? What should we learn from his responses?
Suggested answer
In Isaiah 37 Hezekiah responds to the Assyrian threat with humility and prayer, seeking Isaiah’s counsel and relying on God’s help. In Isaiah 38, facing death, he is more emotional and introspective, pleading for his life. Both show faith, but the contrast reveals that personal crises can challenge faith differently than public ones; trust in God must be cultivated in both spheres, personal and communal.
-
Question 4. Isaiah repeatedly speaks the word of the Lord into dire situations. What role does prophetic truth play when fear and reason seem to contradict faith? Do we have equivalents today?
Suggested answer
Isaiah’s words realign the people with God’s perspective, cutting through fear and human logic. Prophetic truth gives clarity and courage by reminding people of God’s sovereignty and promises. Today that role is carried forward by Scripture, faithful teaching, and Spirit-filled exhortation — truth that confronts the lies of fear and re-centers us on God’s purposes.

God’s Reassurance of Victory
Teaching note
Read verse 35 slowly, then ask the review question: if God had saved them because of their own actions, why would that have been a problem? 2 Samuel 7 and Romans 5 are the cross references to bring up.God answers Hezekiah’s prayer through Isaiah. Sennacherib has defied the Holy One of Israel, but God will put His hook in his nose and turn him back by the way he came; he will not come into the city or shoot an arrow there (37:21–34). And God gives His reason: “For I will defend this city to save it, for mine own sake, and for my servant David’s sake” (verse 35). That night the angel of the Lord struck down 185,000 in the Assyrian camp, and Sennacherib returned to Nineveh, where his own sons killed him (verses 36–38).
God’s promises are eternal; He had made His covenant with David (2 Samuel 7), and He keeps it. God will be glorified, not Judah — exactly what Hezekiah had prayed for (verse 20). God is the deliverer, not Judah (compare Romans 5). And this statement links the preservation and restoration of Jerusalem to the coming of the ultimate Son of David.
-
Question 5. Why do you think God emphasized that He would save Jerusalem “for His own sake and for the sake of David”? What comfort would this have given His people then as well as today?
Suggested answer
God’s actions were rooted in His own glory and His covenant with David (2 Samuel 7), so the deliverance was not earned by Judah’s righteousness but came from His character and promises. His faithfulness does not fluctuate with our merit. That encourages us to trust Him even when we feel unworthy, because He acts out of His unwavering commitment to His name and His word.
-
Question 6. If God had saved them because of their own actions, why would this have been a problem?
Suggested answer
Then Judah, not God, would have had the glory, and their deliverance would have rested on their own merit, which rises and falls with their conduct. Because God saved them for His own sake and for David’s sake, He alone is glorified (37:20) and the deliverance rests on His unchanging promises.

The Healing of Hezekiah
Teaching note
It seems Hezekiah did not respond appropriately to the healing, but eventually humbled himself and the darkness lifted. Stop for discussion on the two slide questions (the sign, and whether he could have done more) before moving to the envoys from Babylon.Hezekiah is given a grave diagnosis: “Set thy house in order; for thou shalt die, and not live” (38:1). And yet he still turns to the Lord for mercy, turning his face to the wall, praying, and weeping sore (verses 2–3). God hears his prayer and sees his tears; He gives him fifteen more years, promises to deliver him and the city from the king of Assyria, and gives a sign — the shadow on the dial of Ahaz goes back ten steps (verses 4–8).
Could Hezekiah have done more in response to the healing? The parallel accounts answer plainly: “Hezekiah rendered not again according to the benefit done unto him; for his heart was lifted up: therefore there was wrath upon him, and upon Judah and Jerusalem” (2 Chronicles 32:25; compare 2 Kings 20:12–13). Yet he humbled himself for the pride of his heart, so that the wrath of the Lord did not come in his days (2 Chronicles 32:26).
-
Question 7. What lessons can we draw from the healing of Hezekiah in chapter 38?
Suggested answer
Even under a grave diagnosis Hezekiah turned to the Lord, and God heard his prayer and saw his tears (38:2–5). His healing was both a personal mercy and a sign to the nation, an encouragement and reaffirmation of God’s power. So too, when believers endure suffering with faith and are shown mercy, their stories edify and strengthen others; private faithfulness and answered prayer can ripple outward to families, churches and communities.
-
Question 8. Why is this sign significant?
Suggested answer
It was the Lord’s own confirmation “that Jehovah will do this thing that he hath spoken” (38:7). Turning back the shadow on the dial is something only the God who made heaven and earth (37:16) could do, so the One who commands the sun could surely add years to Hezekiah’s life and deliver the city.
-
Question 9. Could Hezekiah have done more in response to the healing?
Suggested answer
Yes. He “rendered not again according to the benefit done unto him; for his heart was lifted up,” and wrath came on him and on Judah (2 Chronicles 32:25). Instead of giving God the credit, he showed off his treasures to Babylon (2 Kings 20:12–13). To his credit he later humbled himself, and the wrath did not come in his days (2 Chronicles 32:26).

Hezekiah and Babylon
Teaching note
Merodach-baladan is pronounced MEHR-oh-dak BAL-uh-dan (Berodach-baladan in 2 Kings 20:12). Ask “to whose credit?” before reading verse 2, and let the class find Proverbs 16:18 for “What comes before destruction?”Hezekiah’s recovery became well known — but to whose credit? Merodach-baladan, king of Babylon, sent letters and a present, for he had heard that Hezekiah had been sick and recovered (39:1). Then Hezekiah’s pride took over. He was glad of the envoys and showed them his silver and gold, spices and precious oil, and all his armory: “there was nothing in his house, nor in all his dominion, that Hezekiah showed them not” (verses 2–3).
Isaiah asks who these men were and what they had seen, and then delivers the word of the Lord: all that was in Hezekiah’s house would be carried to Babylon, and some of his own sons would be eunuchs in the palace of the king of Babylon (verses 3–7). What comes before destruction? “Pride goeth before destruction, And a haughty spirit before a fall” (Proverbs 16:18; compare Galatians 6:3). Our legacy is not the riches we accumulate but rather a life of faithful service (2 Timothy 4:7–8).
-
Question 10. Why was Hezekiah’s decision to show the Babylonian envoys all his treasures seen as foolish, and what does this teach us about pride, legacy, and short-sightedness in leadership or personal life?
Suggested answer
Hezekiah’s pride led him to flaunt his wealth and military assets without discernment, perhaps seeking political alliance or personal validation. Isaiah rebuked it because it exposed Judah to future danger and revealed misplaced confidence. It warns us against boasting in our success and failing to consider the long-term spiritual consequences of our decisions, especially those that affect others.
-
Question 11. What comes before destruction?
Suggested answer
Pride: “Pride goeth before destruction, And a haughty spirit before a fall” (Proverbs 16:18). The one who “thinketh himself to be something when he is nothing… deceiveth himself” (Galatians 6:3), as Hezekiah did when his heart was lifted up.
Part 6 · Isaiah 39:8 · 4 min
Babylon’s Invasion Foretold
Teaching note
Present the three views and let the class weigh them before giving the conclusion in the answer below.Hezekiah answers Isaiah, “Good is the word of Jehovah which thou hast spoken. He said moreover, For there shall be peace and truth in my days” (39:8; “At least there will be peace and truth in my days” in many versions). He affirms that God’s word is true and good, showing faithful acceptance, unlike other kings who might have raged or rebelled.
There are a variety of views on his second remark: gratitude for delayed judgment (faithful acceptance), short-sighted comfort (selfish resignation), or a mix of the two. On one hand he trusted God’s word and accepted it; on the other, he seemed content with peace in his own time without interceding for the generations to come.
-
Question 12. After being told of the judgment that would come upon his descendants, Hezekiah responded, “There will be peace and truth in my days.” How do you interpret that response — was it faithful acceptance or selfish resignation? What might we learn from that tension for how we think about future generations?
Suggested answer
His response reflects a mix of relief and troubling apathy. He trusted God’s word and accepted it, but he seemed content with peace in his own time without interceding for future generations. This challenges us to consider whether we are content with spiritual comfort now while neglecting to invest in the faith and well-being of those who come after us.

Lessons for Today
Teaching note
Tie each lesson back to a moment in the chapters: the request for prayer for the remnant (37:4), the healing (38), and the treasures shown to Babylon (39).Our walk in faith should not be a solo journey; God’s works are to be made known “to their children; That the generation to come might know them” (Psalm 78:5–7; Deuteronomy 6:6–7). Prayerful intercession for others is a sign of strength, not weakness (Isaiah 36–37).
Focus on today’s challenges, aware that a tomorrow may come: “So teach us to number our days, That we may get us a heart of wisdom” (Psalm 90:12; James 4:14). And our legacy is not defined by what we accumulate: “Greater joy have I none than this, to hear of my children walking in the truth” (3 John 1:4).
-
Question 13. Across these chapters, how does Hezekiah’s faith both shine and falter? What does his example teach us about the complex nature of spiritual leadership and the grace God shows to imperfect people?
Suggested answer
Hezekiah shines in his prayerfulness, humility and dependence on God during the national crisis, but falters in moments of pride and short-term thinking. His life reflects the real tensions in leadership — courage and compromise, faith and fear. His story reassures us that God honors sincere trust even in flawed people, and that leaders must be held accountable while also being recipients of grace.
