The court is called to order, and heaven and earth are the jury. God stands in His own creation and reads a charge against the children He raised. “Hear, O heavens, and give ear, O earth: for the LORD hath spoken” (Isaiah 1:2). Every lesson from Isaiah 1 starts here, in that courtroom, because this is the chapter that sets the terms for everything that follows.
You know what it is to be charged by someone who loves you. The conversation that began with “we need to talk.” The moment a parent sat you down in grief, not anger. That register, somewhere between a court and a kitchen table, is where Isaiah 1 lives. God is not unmoved. He is a Father reading a case against children He has not stopped loving, which is exactly what makes it hard to sit with.
This article walks through the summary of Isaiah 1, then draws out the lessons from Isaiah 1 that will search your conscience, name what you have been carrying, and show you the door God has already opened.

Summary of Isaiah Chapter 1
Before Isaiah 1: Setting the Stage
Isaiah 1 is the opening statement of a sixty-six chapter prophetic collection. The book names its period: the reigns of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah (Isaiah 1:1), covering roughly 740 to 680 BC, sixty years of one prophet’s ministry. By the time Isaiah steps forward, the northern kingdom of Israel is either already gone or about to fall to Assyria in 722 BC. Judah has watched its sister nation collapse and has not changed course.
Isaiah was a Jerusalem insider: educated, with access to kings, intimate with the temple. His name means “salvation of Yahweh,” and the entire book unpacks that name. Chapter 1 is his opening argument, the prologue that introduces in miniature every major theme the following sixty-five chapters will expand: sin, hollow worship, repentance, covenant consequences, and the promise of restoration.
Location and Time of Isaiah 1
The chapter is addressed to Judah, the southern kingdom, most likely during the reign of Ahaz (735-715 BC), among the most wicked kings in Judah’s history, a man who practiced child sacrifice and made Judah a vassal of Assyria. The surrounding nations were already invading. The land had been partially devastated. Jerusalem remained standing, but barely, like a cottage in a field when the harvest is over and no one is watching it.
One-Word Summary: SUMMONED
Reason: The governing action of Isaiah 1 is God calling His people to stand before Him. Every scene is an aspect of that summons: the call to heaven and earth to witness, the indictment, the rejection of empty worship, the invitation to reason together, the warning, the promise. Everything flows from the fact that God has called court into session.
“Summoned” could not describe Isaiah 6 (commissioned), Isaiah 40 (comforted), or Isaiah 53 (atoned). It belongs to Isaiah 1, where God opens His case and demands that His people stand before the weight of what they have become.
One-Sentence Summary
God summons heaven and earth to witness His case against Judah, charging them with a rebellion more senseless than a donkey’s, describing their condition as a body covered in untreated wounds and their land as a wasteland already being consumed, rejecting their sacrifices and feasts and prayers as an abomination because their hands are full of blood and their hearts have not changed, commanding them instead to cease evil and learn to do good, to seek justice and relieve the oppressed, then offering the most stunning invitation in the chapter: come, let us reason together, and if their sins are as scarlet He will make them white as snow, but if they refuse the sword will devour them, before closing with a lament over Jerusalem the faithful city become a harlot, a promise that God will purge the dross and restore righteous judges, and a warning that those who forsake the LORD will be consumed like a garden without water.
Comprehensive Summary of Isaiah Chapter 1
The Superscription and the Charge (vv. 1-4)
Verse 1 is the title of the whole book: the vision of Isaiah the son of Amoz concerning Judah and Jerusalem across four reigns. Then, without introduction, God speaks. He calls heaven and earth as witnesses, the same cosmic witnesses Moses called in Deuteronomy 32:1, an unmistakable legal echo signalling a covenant lawsuit. The charge comes in two parts: God has nourished and raised children who have rebelled against Him, and even the ox and the donkey, animals proverbial for their stubbornness, know whose manger feeds them. Israel does not know. Israel does not consider.
- The word “rebelled” (Hebrew: pasha) is the language of a vassal breaking covenant with a sovereign, of a son turning against the father who raised him
- “Holy One of Israel” appears for the first time in v.4, a title Isaiah uses 25 times; it appears only 6 times in the entire rest of the Old Testament; it holds together God’s blazing purity and His covenant commitment to this specific people
- The phrase “gone away backward” in v.4 describes a turning away that has become a direction of travel, not a momentary lapse but a settled orientation
The Devastated Land and the Besieged City (vv. 5-9)
Why, Isaiah asks, do you keep inviting more blows? The whole head is sick, the whole heart faint. From foot to head there is no soundness, only wounds and bruises and putrefying sores that have not been treated, not closed, not bound up, not softened with oil. The nation is a body refusing its own treatment.
The land matches the body: cities burned, the ground devoured by strangers. Jerusalem sits alone like a cottage in a vineyard at the end of the season, a lodge in a garden of cucumbers when the season is over. If the LORD of hosts had not preserved a remnant, Judah would have been as Sodom and Gomorrah, entirely.
- The bruised body metaphor (vv.5-6) likely refers to the invasions under Ahaz by Syria, Israel, the Edomites, and the Philistines, described in 2 Chronicles 28
- “The daughter of Zion” (v.8) is a personification of Jerusalem as a vulnerable young woman left exposed and isolated
- The remnant doctrine appears in seed form here (v.9): God preserves a holy seed; without it Judah would have been annihilated. Paul quotes this verse in Romans 9:29
The Rejection of Empty Worship (vv. 10-17)
Calling the rulers of Jerusalem “rulers of Sodom” and the people “people of Gomorrah,” God delivers His most searing word: He is nauseated by their religious activity. Their burnt offerings, their incense, their new moons and appointed feasts, a burden He is weary of bearing. When they spread their hands in prayer, He hides His eyes. When they multiply their prayers, He does not hear. The reason: their hands are full of blood.
Then the command: wash yourselves, make yourselves clean, put away the evil of your doings, cease to do evil, learn to do well, seek judgment, relieve the oppressed, judge the fatherless, plead for the widow.
- The critique is not that sacrifice was wrong. The Law required it. The critique is that sacrifice divorced from justice has become an abomination, a covering operation for an unchanged life
- “Cease to do evil; learn to do well” is sequenced deliberately: cessation comes first; you cannot build well-doing on top of continuing evil
- The specific social categories (oppressed, fatherless, widow) represent those with no legal or social power to defend themselves; God’s people were supposed to be their protection
The Invitation and the Warning (vv. 18-20)
After the indictment, God does not pronounce sentence. He extends an invitation. “Come now, and let us reason together.” Though their sins are scarlet, as permanent as the deepest dye in the ancient world, He can make them white as snow. If they are willing and obedient, they will eat the good of the land. If they refuse and rebel, the sword.
- “Reason together” (Hebrew: yakach) carries legal weight: a formal hearing with a verdict attached, not a friendly chat
- Scarlet and crimson were the most colorfast, permanent dyes in the ancient Near East. God is offering to reverse what is humanly irreversible
- The two outcomes (vv.19-20) are not options God is indifferent between; He is stating what is true about two different paths
The Lament Over Jerusalem and the Promise of Purging (vv. 21-31)
Jerusalem was once the faithful city, full of judgment, righteousness lodged in her. Now she is a harlot. Silver become dross, wine mixed with water, princes running with thieves, bribes loved and gifts chased, the fatherless unjudged, the widow’s cause never heard.
God announces He will ease Himself of His adversaries, purge away the dross, remove the tin, and restore her judges as at the first. Afterward she shall be called the city of righteousness, the faithful city. But those who forsake the LORD shall be consumed: the strong man becomes tinder, his work a spark, and both burn together with none to quench them.
- “Harlot” (v.21) is covenant-breaking language: Jerusalem has committed spiritual adultery against the God she was covenanted to
- The refiner’s imagery (v.25): dross is the impurity that rises to the surface when silver is heated; it cannot be removed without fire
- The final promise (v.26) is the first restoration oracle in the book: the faithful city will be called the faithful city again
Theme of Isaiah Chapter 1
The central theme of Isaiah 1 is the collision between what God’s people have become and what He called them to be, and the fact that the collision does not end in abandonment but in invitation. God opens the book with a summons, not a sentence. He has a case. They have a choice. The choice is still open.
Sub-themes include:
- Ingratitude as the root of rebellion: Israel’s sin begins not with dramatic wickedness but with forgetting who raised them
- Spiritual sickness as a picture of a nation refusing diagnosis: the wounds are visible, the treatment available, the patient will not hold still
- Religious performance as a cover for moral failure: the most dangerous condition is not irreligion but active worship severed from justice
- The remnant doctrine: God always preserves a holy seed; complete destruction is held back by that preserved remnant
- Refinement as the purpose of judgment: God’s intent in purging is restoration; the fire is the refiner’s fire
- The faithful city as both lamentation and promise: what Jerusalem was is the standard; what it will be again is the goal

Lessons from Isaiah 1
Lesson 1: I Have Nourished and Brought Up Children (Isaiah 1:2)
You know what it costs to raise something and watch it walk away without a backward look. The word “nourished” is not abstract. It means nights and meals and years. It means your own strength poured into someone else’s life. And then the child turns away.
That is the register God speaks from in verse 2. Not the cold formality of a judge. The grief of a Father describing the wound of children who have walked out of the house He built for them. “I have nourished and brought up children, and they have rebelled against me.” The Hebrew word for “rebelled” is pasha, the language a son uses when he turns against the father who raised him. This is not law-breaking. This is family-breaking.
And then the comparison that lodges like a splinter: even the ox knows its owner. Even the donkey knows whose manger feeds it. Isaiah’s audience understood exactly what he meant. The ox and donkey were chosen not because they were impressive but because everyone knew they were the most dim-witted creatures on the farm. Even they know who fills the trough. Israel did not.
Before you nod at Israel from a safe distance, sit in it. Think about the doors God opened that you walked through and never looked back at. The answered prayers you stopped remembering once the crisis passed. The seasons of provision you filed under “my hard work” and moved on. Ingratitude rarely announces itself. Sometimes it just looks like forgetting, a life completely sustained by Someone you have stopped considering.
The ox knows its owner. The donkey knows its master’s crib. Does your daily life, in its actual texture, reflect that you know yours?
Lesson 2: The Whole Head Is Sick and the Whole Heart Faint (Isaiah 1:5-6)
You know what it is to be a patient who will not hold still for treatment. The thing you keep going back to even though you know the cost. The pattern with a name you recognize and a history you could trace, and you are still in it, not committed to the wound being permanent, but not committed to healing either. Managing it.
That is what Isaiah describes in verses 5 and 6, not as a moral category but as a medical image. “From the sole of the foot even unto the head there is no soundness in it; but wounds, and bruises, and putrifying sores: they have not been closed, neither bound up, neither mollified with ointment.” The wounds are real. The ointment exists. The patient refuses treatment.
The question underneath verse 5 makes it personal: “Why should ye be stricken any more? ye will revolt more and more.” God is not asking in contempt. He is asking the way a doctor asks someone who keeps pulling out their own stitches. You have seen what this produces. You know the result of the last time. Why, knowing what you know, is the response more of the same?
The answer is that sin has its own logic. Once you are deep enough in, the wound becomes familiar, the pain becomes background noise, and the idea that something could actually be different becomes harder to hold than the easier idea that this is simply how things are. You stop expecting the wound to close. You organize your life around it instead.
Isaiah does not offer sympathy for the management strategy. He names it as a refusal. The first movement toward healing is not feeling better about the wound. It is stopping the behavior that keeps it open.

Lesson 3: Your New Moons and Your Appointed Feasts My Soul Hateth (Isaiah 1:14)
You attend. You give when the offering is taken. You know the right words and say them at the right moments. You raise your hands on Sunday. And the rest of your life runs on its own separate logic: how you treat the person below you at work, what you do with money that could reach the poor, whether you pursue justice or simply protect your comfort. that your Sunday never touches. You have made a peace with that separation. You call the Sunday portion “my spiritual life” and leave it there.
God calls it an abomination. That is the actual word He uses in verse 13. “Bring no more vain oblations; incense is an abomination unto me; the new moons and sabbaths, the calling of assemblies, I cannot away with; it is iniquity, even the solemn meeting.”
Israel was not irreligious. That is the sting of this passage. The sacrifices were being brought, the feasts observed, the incense burned, hands spread in prayer. The religious machinery was running on schedule. And God says He is weary of bearing it. When they prayed, He hid His eyes. The reason is devastating in its simplicity: “your hands are full of blood” (v.15). The same hands spread toward heaven on the Sabbath were soaked in the injustice of the other six days.
They had learned to segment a life that God refuses to receive in segments. He does not accept the religious portion while the rest remains unexamined. He accepts the whole person or He calls the offering what it is: a performance designed to satisfy the obligation without changing the life.
Most people reading this are not in danger of irreligion. They are in danger of exactly this. The religion is real. The separation is also real. And Isaiah 1 will not let both things be acceptable at once.

Lesson 4: Cease to Do Evil; Learn to Do Well (Isaiah 1:16-17)
Think about the last time you tried to build a new habit on top of an unchanged life. The reading plan that lasted two weeks because nothing else shifted. The new pattern grafted onto the same soil producing the old one for years. The new thing does not take root. The old thing reasserts itself. You end up discouraged, not because you lacked commitment but because you tried to skip the first step.
The sequence in verse 16 is not accidental. “Cease to do evil” comes before “learn to do well.” These are not two simultaneous tracks. They are ordered. Cessation is the foundation. The soil has to be cleared before the new seed can take. That order is not a discouragement. It is a mercy. It tells you exactly where to start.
Then God gets specific: seek judgment, relieve the oppressed, judge the fatherless, plead for the widow. These are not abstract spiritual disciplines. They are categories of real people with no legal standing, no social protection, no one to speak on their behalf. God’s people had everything required to stand for those people. They were using it for themselves.
Well-doing in Isaiah 1 has an address. The measure of whether your repentance is real is not whether you feel differently about your sin. It is whether you move differently toward those people. The walk with God that Isaiah describes is not private. It is visible in the direction you face.

Lesson 5: Though Your Sins Be as Scarlet, They Shall Be as White as Snow (Isaiah 1:18)
You have something you consider scarlet. Something you decided, quietly, that God cannot fully reverse. You received the forgiveness in doctrine years ago. You still carry the stain in practice. You define yourself partially by it. You lower your voice when certain topics come up because you know what sits in your history and have concluded, without quite meaning to, that it disqualifies you from certain things.
After the indictment. After the rejected worship. After the diseased body and the ruined land. After all of that, God says something that has been stopping readers cold for twenty-seven centuries: “Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.”
Scarlet and crimson were the most permanent dyes in the ancient world, a metaphor not for embarrassing sins but for the kind of stain no human process can undo. And God says: I can make it as though it was never there. Complete reversal. The absence of the stain altogether.
The word “come” in verse 18 carries the weight of a genuine appeal. God is not dragging the accused into the dock. He is extending His hand first. The God who just laid out a prosecution that should have ended in a final verdict is leaning across the table saying: come. Let us reason this through. That is not the posture of a God who has given up. That is the posture of a Father who has not.

What is the scarlet thing you have stopped believing God can fully reverse? What would it mean today not to confess it again as though the first repentance failed, but simply to receive what He already offered: to accept the whiteness and stop wearing the stain He has already removed?
Lesson 6: If Ye Be Willing and Obedient (Isaiah 1:19-20)
You already know that obedience and disobedience are not the same road. You know it the way you know that fire burns, not as theory but as something you have felt. You have seen what refusal costs. You have watched a season close that could have been different. And still there is something God has been asking that you have not said yes to. Not because you misunderstood. Because the yes would cost something you are still holding.
After the scarlet-and-snow promise of verse 18, God does not drift into sentiment. He states exactly what the two responses produce. “If ye be willing and obedient, ye shall eat the good of the land.” Then, without pause: “But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the LORD hath spoken it.”
Two words carry the whole weight: willing and refuse. The line is not drawn between the righteous and the wicked. It is drawn between willing and refusing, a line of orientation, not performance. A willing heart that stumbles is still moving toward God. A refusing heart that keeps its religious schedule is still moving away.
Notice what is attached to willingness: obedient. The two travel together. Willingness without obedience is sentiment. Obedience without willingness is duty already beginning to rot. What God is asking for is both: the heart that wants to and the hands that do. That combination, Isaiah says, unlocks the good of the land. And “for the mouth of the LORD hath spoken it” is not a flourish. It is a divine certainty structured around one variable: your choice.

What is the thing God has been asking that you are still holding back from. Not the thing you are confused about,, but the thing you know He wants and have not yet said yes to? What would willing obedience look like today, in one concrete act?
Lesson 7: How Is the Faithful City Become an Harlot (Isaiah 1:21)
Think about the gap between who you were when you first came to God and who you are now in the parts of your life no one sees. The slow drift. The values that shifted so gradually you cannot name the day they moved. The lines that moved so incrementally you did not feel yourself cross them. You kept the name. You kept the schedule. The content changed.
That is the specific grief of Isaiah’s lament in verse 21. The grief is not that Jerusalem became openly pagan. It is that she kept the name while the reality quietly left. “How is the faithful city become an harlot! it was full of judgment; righteousness lodged in it; but now murderers.” Silver become dross. Wine mixed with water. The princes protecting the vulnerable are running with thieves, taking bribes, and the widow’s cause never reaches the court.
The word “harlot” is covenant language. This is not a stranger who never knew God falling into sin. This is someone who took vows and broke them while still attending the ceremony. The depth of the betrayal is proportional to the depth of the original commitment. A city never covenanted to God could not become a harlot. Only Jerusalem could fall this specific way, and only a person who truly came to God, made real commitments, and then drifted can fall this specific way too.
The danger for long-term Christians is not dramatic apostasy. It is the slow divergence between the label and the life, the name and the reality, the person you present on Sunday and the person your closest relationships actually deal with. Isaiah’s lament is a mirror, not a verdict. The question it holds up is whether you still are what you say you are.

Lesson 8: I Will Purely Purge Away Thy Dross (Isaiah 1:25)
You are in a season that does not make sense yet. Something you built is collapsing, or something you relied on has been removed, or something you managed to keep covered is being exposed, and you have been praying for the exit since it began. What if the thing you are praying to escape is the thing God is using on purpose?
When God says in verse 25, “I will turn my hand upon thee, and purely purge away thy dross, and take away all thy tin,” this is not the language of a God who has abandoned the city. It is the language of a refiner who refuses to watch his silver become worthless. Dross is what rises to the surface when silver is heated, the impurities fused into the metal that cannot be removed by any cold process. You cannot pick it out by hand. The only way is fire.
God’s stated intention is restoration, not destruction. He will remove the corrupt judges and the bribe-takers not to empty Jerusalem but to make it capable again of being what it was called to be. The refiner does not put silver in the furnace because he has given up on it. He puts it in because he has not.
Every hard season is not a refiner’s fire. But some are. When you can locate what God is purging, the fire begins to make a different kind of sense: the dependency that was never supposed to be a foundation, the pattern He has been trying to remove for years, the impurity that kept rising to the surface.

Lesson 9: Thou Shalt Be Called the City of Righteousness, the Faithful City (Isaiah 1:26)
There is a promise over your life that the distance between here and there has made you stop holding. Not because it was unclear when it came. Because the gap between what was spoken and where you currently stand has become so wide that holding it feels more like denial than faith. You still believe it in theory. You have stopped expecting it in practice.
After the indictment, after the lament, after the purging fire, the chapter ends not in judgment but in this: “Afterward thou shalt be called, The city of righteousness, the faithful city.” The word “afterward” is doing enormous work. After the purging. After the dross has been removed. Afterward, the name will match the reality again. The promise is not being revised by the current condition. It is being processed through it.
Judgment is never the last word. The last word is always restoration. The reason Isaiah can speak the promise in the same breath as the indictment is that both come from the same God, the One who disciplines because He has not let go, who prosecutes because abandonment would have been easier and He will not do it. The indictment itself is an act of love. A God who had given up on Jerusalem would not summon heaven and earth to witness. He would simply leave.
The summons means He is still there. The case means He still has plans. What God has promised, He finishes.
READ ALSO: Nehemiah Chapter 1: When God Decides to Rebuild
Write down one thing God has promised you that the current distance from it has made you stop believing. Read Isaiah 1:26 beside it. God does not restore what He was never serious about. What would it mean to take that promise off the shelf today?
Lesson 10: The Strong Shall Be as Tow (Isaiah 1:31)
You built something without God at the center of it. You know which thing: the relationship, the career structure, the financial position, the reputation. The thing you chose when choosing it meant not choosing Him. It felt like strength when you built it. It has the appearance of stability. And the chapter closes with God naming exactly what that kind of strength becomes: tow. Dry flax. The most combustible material in the ancient world. And the maker of it becomes the spark.
“And the strong shall be as tow, and the maker of it as a spark, and they shall both burn together, and none shall quench them” (Isaiah 1:31). The strong man is not destroyed by an outside enemy. He is destroyed by the combination of what he built and what he became in building it. His work is the fuel. He is the ignition. And there is no one to put it out because he chose everything that would have put it out.
The oaks of verses 29-30 make this specific. The people had worshipped in sacred groves, gardens chosen for their idolatry. Now those oaks, the very things they ran to, will be their shame. The leaf of the oak fades. The garden without water withers. The thing you chose instead of God does not ultimately sustain you. It eventually becomes the evidence of what you chose.
There is a version of a life that looks strong from the outside and is tow on the inside, built on reputation instead of character, on achievement instead of obedience, on the appearance of fruitfulness without the root that produces fruit. It holds together until the fire comes. And when it burns, it burns fast, completely, with no one to put it out because there was nothing in it that belonged to God.
Isaiah 1 is a mercy for ending here. The strong man has not been consumed yet. The spark has not landed. The chapter is still open. And the same God who said scarlet sins can become white as snow is still asking: come, let us reason together, before the tow catches.

Closing Thoughts on Isaiah 1
Isaiah 1 does not rush to comfort. It earns the right to offer it by refusing to pretend everything is fine when it is not. It holds you in the courtroom long enough for the mirror to do its work, long enough to feel the weight of being compared unfavorably to a donkey, long enough to sit with the image of a diseased body that will not hold still for treatment, long enough to hear God say He is weary of the very worship you thought was keeping you in good standing.
And then it opens the door. Come now. Let us reason together. Scarlet becoming snow. Crimson becoming wool. Total reversal of what no human process could undo.
The whole chapter turns on one word in verse 19: willing. A heart turned toward God. That is the only qualification. That posture is what the good of the land runs through. The absence of it is what the sword runs through. The line between the two is not performance. It is direction.
Sixty-five chapters follow this one. The Holy One of Israel introduced in verse 4 will be seen on His throne in chapter 6. The servant hinted at in the remnant doctrine will appear in his full suffering glory in chapter 53. The faithful city promised in verse 26 will become the new Jerusalem of chapters 60 through 66. Isaiah 1 is a doorway. Walk through it honestly and you will read everything that follows differently.
The court is still in session. The invitation is still open. Come, let us reason together.
Frequently Asked Questions About Isaiah 1
What is the main message of Isaiah 1?
The main message of Isaiah 1 is that God’s people have broken their covenant relationship through rebellion, injustice, and hollow religious performance, and that God responds not with immediate destruction but with a summons to come and reason together. He offers complete forgiveness on condition of willing obedience: “though your sins be as scarlet, they shall be as white as snow”, while stating plainly that continued rebellion leads to the sword. The chapter holds both the full weight of the indictment and the full generosity of the invitation without softening either.
What does it mean that Israel’s sins are scarlet in Isaiah 1:18?
Scarlet and crimson were the most permanent, colorfast dyes in the ancient Near East. They did not fade with washing or time. When God says their sins are as scarlet, He is describing their permanence: stains that no human process can reverse. The power of the promise is that God is not offering to fade something that might wash out on its own. He is offering to make permanently stained things white as snow, a reversal that only divine action can accomplish. This is why the verse has carried such weight across centuries of preaching on grace.
Why does God reject Israel’s sacrifices and worship in Isaiah 1?
God rejects their worship not because sacrifice was wrong in itself, the Law required it, but because it had been completely severed from justice and heart transformation. The people were offering religious performance while their hands were “full of blood,” meaning they were oppressing the poor, taking bribes, and ignoring the fatherless and the widow. Worship offered by hands full of the blood of injustice is not acceptable worship. It is an abomination that insults rather than honours Him.
What is the “faithful city” in Isaiah 1?
The faithful city is Jerusalem, named for what it once was and promised as what it will be again. In verse 21, Isaiah laments that the city once “full of judgment” where “righteousness lodged” has become a harlot, her leaders corrupt, her courts for sale. In verse 26, God promises to restore her judges and counselors, and after the purging she will again be called the city of righteousness, the faithful city. The phrase forms a literary bracket around the lament: this is what she was, this is what she became, this is what God will make her again.
Who is the remnant in Isaiah 1:9?
The remnant in Isaiah 1:9 is the small number of faithful Israelites whose preservation by God keeps the nation from being entirely consumed like Sodom and Gomorrah. God never allows the total destruction of His covenant people. He always preserves a holy seed through which restoration becomes possible. Paul quotes Isaiah 1:9 directly in Romans 9:29 to argue that faithful Jewish believers in his own day are proof that God has not cast away His people.
