Verse-by-Verse Commentary
The Book of Isaiah
Chapter 37: Hezekiah Spread It Before the LORD
Chapter 37 is the answer to chapter 36's threat, and it turns on prayer. When the Assyrian blasphemy reaches Hezekiah, he does not send for reinforcements; he tears his clothes, goes 'into the house of the LORD,' and takes the crisis to God and to the prophet Isaiah. When Sennacherib sends a threatening letter, Hezekiah 'spread it before the LORD' and prayed, 'thou art the God, even thou alone.' God answers through Isaiah with a stinging word against the proud king, promising 'I will defend this city to save it,' and that night 'the angel of the LORD went forth, and smote in the camp of the Assyrians a hundred and fourscore and five thousand.'

Setting the Stage
Into the House of the LORD
Hezekiah tears his clothes, goes to the temple, and sends to Isaiah; Isaiah answers, "Be not afraid."
Spread It Before the LORD
Hezekiah spreads Sennacherib's letter before the LORD and prays, "thou art the God, even thou alone."
I Will Defend This City
God rebukes the proud king through Isaiah and vows, "I will defend this city to save it for mine own sake."
The Angel Went Forth
In one night the angel of the LORD smites 185,000 Assyrians; Sennacherib flees home and falls by the sword.
Into the House of the LORD (Isaiah 37:1-7)
Hearing the blasphemy, Hezekiah humbles himself, goes to the temple, and sends to Isaiah for prayer, confessing his utter helplessness, and God answers at once, "Be not afraid."
A Day of Trouble
"And it came to pass, when king Hezekiah heard it, that he rent his clothes, and covered himself with sackcloth, and went into the house of the LORD. And he sent Eliakim, who was over the household, and Shebna the scribe, and the elders of the priests covered with sackcloth, unto Isaiah the prophet the son of Amoz. And they said unto him, Thus saith Hezekiah, This day is a day of trouble, and of rebuke, and of blasphemy: for the children are come to the birth, and there is not strength to bring forth. It may be the LORD thy God will hear the words of Rabshakeh, whom the king of Assyria his master hath sent to reproach the living God, and will reprove the words which the LORD thy God hath heard: wherefore lift up thy prayer for the remnant that is left. So the servants of king Hezekiah came to Isaiah. And Isaiah said unto them, Thus shall ye say unto your master, Thus saith the LORD, Be not afraid of the words that thou hast heard, wherewith the servants of the king of Assyria have blasphemed me. Behold, I will send a blast upon him, and he shall hear a rumour, and return to his own land; and I will cause him to fall by the sword in his own land."
Word Study
"the children are come to the birth, and there is not strength to bring forth." A vivid image of total helplessness: like a mother in labor who has no strength left to deliver. Hezekiah confesses he is at the point of crisis with no power of his own to bring it through, exactly where God loves to work.
"the living God," el chai (אֵל חָי). The title that separates the LORD from every idol. Hezekiah and Isaiah both seize on the fact that Rabshakeh has "reproach[ed] the living God", not a carved image but the God who lives, and who therefore hears and acts.
Explanation
Hezekiah's first move is the right one: "when king Hezekiah heard it," he "rent his clothes... and went into the house of the LORD." He does not panic or send for Egypt; he goes to God. Then he sends his officials, in sackcloth, to Isaiah with a humble, honest confession: "This day is a day of trouble, and of rebuke, and of blasphemy," and the raw admission, "there is not strength to bring forth." He is helpless, and he says so. But he fastens his hope on one thing, that Rabshakeh has "reproach[ed] the living God," and asks Isaiah to "lift up thy prayer for the remnant that is left." God's answer through Isaiah is immediate and calm: "Be not afraid of the words that thou hast heard, wherewith the servants of the king of Assyria have blasphemed me." God takes the blasphemy personally, "blasphemed me," and promises to deal with Sennacherib: "I will send a blast upon him... and I will cause him to fall by the sword in his own land." The whole outcome is announced before a single thing has happened.
Gospel Focus
Hezekiah shows us what to do in "a day of trouble." He took it straight to "the house of the LORD." When the threat is bigger than we are, the first step is not strategy but the sanctuary, "in the time of trouble he shall hide me in his pavilion" (Psalm 27:5). And notice his honesty: "there is not strength to bring forth." He did not pretend to have it handled. God is not looking for our competence but our dependence; "my strength is made perfect in weakness" (2 Corinthians 12:9). The place of no strength is exactly where God's power shows up. See too how God receives the insult against Himself: "wherewith the servants of the king of Assyria have blasphemed me." When the world mocks your faith, it is not finally you they mock but the living God, and He will answer it in His time. And hear the first word He speaks into the crisis: "Be not afraid." It is the word He speaks again and again to His frightened people, and the word the risen Christ still speaks, "Fear not; I am the first and the last" (Revelation 1:17). When you are helpless and afraid, run to the house of the LORD, tell Him honestly you have no strength, and let Him say to you, "Be not afraid."
Spread It Before the LORD (Isaiah 37:8-20)
Sennacherib sends a letter renewing his blasphemous threats, and Hezekiah answers it not with a reply to the king but by carrying the letter into the temple, spreading it out before God, and praying one of the great prayers of Scripture.
Thou Art the God, Even Thou Alone
"So Rabshakeh returned, and found the king of Assyria warring against Libnah: for he had heard that he was departed from Lachish. And he heard say concerning Tirhakah king of Ethiopia, He is come forth to make war with thee. And when he heard it, he sent messengers to Hezekiah, saying, Thus shall ye speak to Hezekiah king of Judah, saying, Let not thy God, in whom thou trustest, deceive thee, saying, Jerusalem shall not be given into the hand of the king of Assyria. Behold, thou hast heard what the kings of Assyria have done to all lands by destroying them utterly; and shalt thou be delivered? Have the gods of the nations delivered them which my fathers have destroyed, as Gozan, and Haran, and Rezeph, and the children of Eden which were in Telassar? Where is the king of Hamath, and the king of Arphad, and the king of the city of Sepharvaim, Hena, and Ivah? And Hezekiah received the letter from the hand of the messengers, and read it: and Hezekiah went up unto the house of the LORD, and spread it before the LORD. And Hezekiah prayed unto the LORD, saying, O LORD of hosts, God of Israel, that dwellest between the cherubims, thou art the God, even thou alone, of all the kingdoms of the earth: thou hast made heaven and earth. Incline thine ear, O LORD, and hear; open thine eyes, O LORD, and see: and hear all the words of Sennacherib, which hath sent to reproach the living God. Of a truth, LORD, the kings of Assyria have laid waste all the nations, and their countries, And have cast their gods into the fire: for they were no gods, but the work of men's hands, wood and stone: therefore they have destroyed them. Now therefore, O LORD our God, save us from his hand, that all the kingdoms of the earth may know that thou art the LORD, even thou only."
Word Study
"spread it before the LORD," yiphroshehu (יִּפְרְשֵׂהוּ). Hezekiah literally opened the scroll and laid it out flat in the temple, as if to say, "Lord, read this for yourself." It is one of the most touching pictures of prayer in the Bible: bringing the very words of the threat and placing them in God's hands.
"thou art the God, even thou alone," attah hu ha-Elohim levaddekha (אַתָּה־הוּא הָאֱלֹהִים לְבַדֶּךָ). The heart of Hezekiah's prayer and of biblical faith: there is one God, and He alone. The Assyrian had lumped the LORD with the idols; Hezekiah answers that the LORD alone is God over "all the kingdoms of the earth," the Maker of heaven and earth.
Explanation
Sennacherib, distracted by an Egyptian army, sends a letter to finish the psychological attack: "Let not thy God, in whom thou trustest, deceive thee." He repeats the same blasphemy, no god of any nation has delivered its land, "and shalt thou be delivered?" Then comes the model response. Hezekiah "received the letter... and read it: and Hezekiah went up unto the house of the LORD, and spread it before the LORD." He answers the king by appealing to the King of kings. His prayer is a masterpiece. He begins with who God is: "O LORD of hosts, God of Israel, that dwellest between the cherubims, thou art the God, even thou alone... thou hast made heaven and earth." He asks God to hear the insult: "hear all the words of Sennacherib, which hath sent to reproach the living God." He concedes the enemy's power honestly, Assyria really has destroyed nations, but names the reason: their gods "were no gods, but the work of men's hands, wood and stone." And he closes with the true motive of the request: "save us from his hand, that all the kingdoms of the earth may know that thou art the LORD, even thou only." He asks not merely for rescue but for God's glory.
Gospel Focus
"Hezekiah... spread it before the LORD." This is a pattern for every believer facing a threat too big to answer. Do not sit and stew over the letter; take it into the presence of God and spread it out before Him. "Casting all your care upon him; for he careth for you" (1 Peter 5:7); "in every thing by prayer and supplication... let your requests be made known unto God" (Philippians 4:6). Bring the actual thing, the diagnosis, the bill, the cruel message, and lay it open before the Lord. And notice the shape of Hezekiah's prayer, for it teaches us how to pray: he begins with worship ("thou art the God, even thou alone"), moves to God's concern ("reproach the living God"), states the problem honestly, and asks for deliverance chiefly so that God will be glorified, "that all the kingdoms of the earth may know that thou art the LORD, even thou only." That closing line is the Oneness heart of the whole prayer: there is one God, "even thou only," the Maker of heaven and earth, who came to us in Jesus Christ. When we pray for our own crises to end in God's glory rather than merely our comfort, we are praying Hezekiah's prayer, and it is a prayer God delights to answer.
I Will Defend This City (Isaiah 37:21-35)
God answers Hezekiah's prayer through Isaiah with a withering word against Sennacherib's pride, reminding him that his conquests were God's doing all along, and vowing to turn him back by the way he came and to defend Jerusalem for His own sake.
For Mine Own Sake, and for David's Sake
"Then Isaiah the son of Amoz sent unto Hezekiah, saying, Thus saith the LORD God of Israel, Whereas thou hast prayed to me against Sennacherib king of Assyria: This is the word which the LORD hath spoken concerning him; The virgin, the daughter of Zion, hath despised thee, and laughed thee to scorn; the daughter of Jerusalem hath shaken her head at thee. Whom hast thou reproached and blasphemed? and against whom hast thou exalted thy voice, and lifted up thine eyes on high? even against the Holy One of Israel. By thy servants hast thou reproached the Lord, and hast said, By the multitude of my chariots am I come up to the height of the mountains, to the sides of Lebanon; and I will cut down the tall cedars thereof, and the choice fir trees thereof: and I will enter into the height of his border, and the forest of his Carmel. I have digged, and drunk water; and with the sole of my feet have I dried up all the rivers of the besieged places. Hast thou not heard long ago, how I have done it; and of ancient times, that I have formed it? now have I brought it to pass, that thou shouldest be to lay waste defenced cities into ruinous heaps. Therefore their inhabitants were of small power, they were dismayed and confounded: they were as the grass of the field, and as the green herb, as the grass on the housetops, and as corn blasted before it be grown up. But I know thy abode, and thy going out, and thy coming in, and thy rage against me. Because thy rage against me, and thy tumult, is come up into mine ears, therefore will I put my hook in thy nose, and my bridle in thy lips, and I will turn thee back by the way by which thou camest. And this shall be a sign unto thee, Ye shall eat this year such as groweth of itself; and the second year that which springeth of the same: and in the third year sow ye, and reap, and plant vineyards, and eat the fruit thereof. And the remnant that is escaped of the house of Judah shall again take root downward, and bear fruit upward: For out of Jerusalem shall go forth a remnant, and they that escape out of mount Zion: the zeal of the LORD of hosts shall do this. Therefore thus saith the LORD concerning the king of Assyria, He shall not come into this city, nor shoot an arrow there, nor come before it with shields, nor cast a bank against it. By the way that he came, by the same shall he return, and shall not come into this city, saith the LORD. For I will defend this city to save it for mine own sake, and for my servant David's sake."
Word Study
"my hook in thy nose, and my bridle in thy lips." The Assyrians themselves led captives by hooks through the lip or nose, a cruelty pictured on their monuments. God turns their own image back on them: the great conqueror will be led home like a captive beast, humiliated by the God he mocked.
"for mine own sake, and for my servant David's sake." The deliverance rests not on Judah's worthiness but on God's own name and His covenant promise to David, "of the fruit of thy body will I set upon thy throne" (Psalm 132:11). That covenant runs on to Christ, the Son of David; God saves for the sake of His own faithfulness.
Explanation
God's answer opens by noting the ground of it: "Whereas thou hast prayed to me against Sennacherib." Because Hezekiah prayed, God acts. The oracle then pours contempt on the proud king: "The virgin, the daughter of Zion, hath despised thee, and laughed thee to scorn." God asks the piercing question, "Whom hast thou reproached and blasphemed?... even against the Holy One of Israel." Sennacherib had boasted that by his own chariots he climbed the mountains and dried up rivers, but God exposes the truth: every conquest Assyria made, God had planned "of ancient times" and "brought it to pass." The mighty empire was only a tool in God's hand, and now the tool has exalted itself against the Maker. So God will lead him home like a hooked animal: "I will put my hook in thy nose... and I will turn thee back by the way by which thou camest." He gives Hezekiah a sign of restored harvests and a promise that a remnant will "take root downward, and bear fruit upward," for "the zeal of the LORD of hosts shall do this." And the great promise lands: "He shall not come into this city... For I will defend this city to save it for mine own sake, and for my servant David's sake."
Gospel Focus
The center of God's answer is the exposure of pride. Sennacherib boasted, "By the multitude of my chariots am I come up," and "with the sole of my feet have I dried up all the rivers," as if his power were his own. God's reply is that the conqueror was only an axe in the Maker's hand, "shall the axe boast itself against him that heweth therewith?" (Isaiah 10:15). All human greatness that forgets it is borrowed is racing toward a fall, for "God resisteth the proud" (James 4:6). But the sweetest words are the ground of the deliverance: "for mine own sake, and for my servant David's sake." God did not save Jerusalem because Judah had earned it, but for His own name and His covenant with David. This is how God saves us too, "not by works of righteousness which we have done, but according to his mercy" (Titus 3:5), "for his name's sake" (Psalm 23:3), and for the sake of great David's greater Son, Jesus Christ, the Son of David in whom the covenant is fulfilled. Your salvation does not rest on your worthiness but on His faithfulness. He defends His own "for mine own sake," and no proud power, no matter how many chariots it counts, can overturn what the zeal of the LORD of hosts has purposed to do.
The Angel of the LORD Went Forth (Isaiah 37:36-38)
God keeps His word in a single night: one angel destroys the vast Assyrian army, Sennacherib slinks home defeated, and the blasphemer is struck down by his own sons while worshiping his powerless idol.
They Were All Dead Corpses
"Then the angel of the LORD went forth, and smote in the camp of the Assyrians a hundred and fourscore and five thousand: and when they arose early in the morning, behold, they were all dead corpses. So Sennacherib king of Assyria departed, and went and returned, and dwelt at Nineveh. And it came to pass, as he was worshipping in the house of Nisroch his god, that Adrammelech and Sharezer his sons smote him with the sword; and they escaped into the land of Armenia: and Esarhaddon his son reigned in his stead."
Word Study
"the angel of the LORD," malakh YHWH (מַלְאַךְ יְהוָה). A single messenger of God accomplishes what no human army could. The One who "smote" Egypt at Passover now smites Assyria; the deliverance is entirely God's, "not of a mighty man" (Isaiah 31:8), fulfilling His word to the letter.
"the house of Nisroch his god." The proud king who mocked the living God as no better than an idol is murdered in the temple of his own idol, which could not protect him. The blasphemy of chapter 36 is answered with poetic exactness: the impotent god he trusted stood by while his sons cut him down.
Explanation
The word of God comes to pass without delay. "Then the angel of the LORD went forth, and smote in the camp of the Assyrians a hundred and fourscore and five thousand." One angel, one night, 185,000 of the world's most feared army, and "when they arose early in the morning, behold, they were all dead corpses." No arrow was shot from Jerusalem's wall; God did it exactly as He had promised in Isaiah 31:8, "not of a mighty man." Sennacherib, who had shouted that no god could deliver Jerusalem, "departed, and went and returned, and dwelt at Nineveh", crawling home in defeat. And the end fits the crime with terrible precision: "as he was worshipping in the house of Nisroch his god," the very idol he trusted, "his sons smote him with the sword." The god who could not save him stood by while he was murdered before it. The living God had the last word, and the blasphemer's own house of idols became his tomb.
Gospel Focus
The deliverance of Jerusalem is a thunderous demonstration that God saves by His own hand, without the arm of flesh. One angel undid an empire, "there is no restraint to the LORD to save by many or by few" (1 Samuel 14:6). Whatever army is arrayed against God's purpose, He needs no help to scatter it. And the death of Sennacherib is a sober parable of the end of all who exalt themselves against the living God. He mocked the LORD as no better than the idols of the nations, and he died at the feet of his own idol, which could not save him. "Be not deceived; God is not mocked" (Galatians 6:7). Every proud power that blasphemes God is on the same road; the story always ends with the living God vindicated and the idol exposed as helpless. For God's people, the lesson is pure comfort: the God who answered one man's prayer by destroying an army in a night is the same God we serve. The threats that tower over you now can be gone by morning at His word. Spread your letter before the Lord, and trust the God who saves alone, for "if God be for us, who can be against us?" (Romans 8:31).
Chapter 37 in Review
Isaiah 37 is the answer to the threat of chapter 36, and it turns entirely on prayer. Hezekiah meets the blasphemy not with panic but by going "into the house of the LORD" and sending to Isaiah, confessing honestly, "there is not strength to bring forth." When Sennacherib's threatening letter comes, Hezekiah "spread it before the LORD" and prayed one of the great prayers of Scripture, "thou art the God, even thou alone... save us from his hand, that all the kingdoms of the earth may know that thou art the LORD, even thou only." God answers through Isaiah with a crushing word against the proud king, exposing that all his conquests were God's doing, vowing to lead him home like a hooked beast, and promising, "I will defend this city to save it for mine own sake, and for my servant David's sake." That night "the angel of the LORD went forth, and smote in the camp of the Assyrians a hundred and fourscore and five thousand," and the blasphemer crept home to die at the feet of his own idol.
For the Apostolic reader this chapter is a school of prayer and a display of the one true God. Hezekiah teaches us to take our trouble to the sanctuary, to spread the very letter of the threat before the Lord, and to pray for God's glory above our own comfort, "that all the kingdoms of the earth may know that thou art the LORD, even thou only." That confession, "thou art the God, even thou alone," is the Oneness heart of the chapter: one God, the Maker of heaven and earth, who came to us in Jesus. God saves "for mine own sake, and for my servant David's sake," not by our merit but by His faithfulness and His covenant fulfilled in the Son of David. And He saves by His own hand, one angel undoing an empire, so that no proud power and no idol can stand. Spread your letter before the Lord, pray for His glory, and trust the God who saves alone.
- In "a day of trouble" Hezekiah went to "the house of the LORD" and confessed his helplessness, and God said, "Be not afraid" (37:1, 3, 6; Psalm 27:5; 2 Corinthians 12:9).
- He "spread it before the LORD", the model of bringing the very threat into God's presence in prayer (37:14; 1 Peter 5:7; Philippians 4:6).
- "Thou art the God, even thou alone... thou only", the one God, Maker of heaven and earth, distinct from every idol (37:16, 20).
- God saves "for mine own sake, and for my servant David's sake", by His faithfulness and covenant, not our merit (37:35; Titus 3:5; Psalm 23:3).
- One angel destroyed 185,000: God saves by His own hand, and the blasphemer died at his idol's feet (37:36-38; 1 Samuel 14:6; Galatians 6:7).
Questions for Reflection
- When trouble comes, is your first move the sanctuary and prayer, or strategy and worry?
- What "letter" do you need to spread before the LORD, laying the actual threat open in His presence?
- Do your prayers aim mostly at your own comfort, or, like Hezekiah's, at God's glory, "that all... may know that thou art the LORD"?
- How does knowing God saves "for mine own sake," by His faithfulness rather than your worthiness, steady your confidence?
References & Sources
Scripture is quoted from the King James Version (KJV). This chapter closely parallels 2 Kings 19 and is summarized in 2 Chronicles 32. The destruction of Sennacherib's army (about 701 BC) is recorded in Scripture and reflected in the Greek historian Herodotus, who preserved a garbled memory of a sudden disaster in the Assyrian camp; Sennacherib's own annals, tellingly, never claim the capture of Jerusalem. His murder by his sons (verse 38) is confirmed in Assyrian and Babylonian records, and Esarhaddon did succeed him. Isaiah 31:8 had already promised the Assyrian would fall "not of a mighty man."
