Commentary on Isaiah 1 verses 21–31
Here, I. The woeful degeneracy of Judah and Jerusalem is sadly lamented. See, 1. What the royal city had been, a faithful city, faithful to God and the interests of his kingdom among men, faithful to the nation and its public interests. It was full of judgment; justice was duly administered upon the thrones of judgment which were set there, the thrones of the house of David, Psa 122:5. Men were generally honest in their dealings, and abhorred to do an unjust thing. Righteousness lodged in it, was constantly resident in their palaces and in all their dwellings, not called in now and then to serve a turn, but at home there. Note, Neither holy cities nor royal ones, neither places where religion is professed nor places where government is administered, are faithful to their trust if religion do not dwell in them. 2. What it had now become. That beauteous virtuous spouse was now debauched, and become an adulteress; righteousness no longer dwelt in Jerusalem (terras Astraea reliquit - Astrea left the earth); even murderers were unpunished and lived undisturbed there; nay, the princes themselves were so cruel and oppressive that they had become no better than murderers; an innocent man might better guard himself against a troop of banditti or assassins than against a bench of such judges. Note, It is a great aggravation of the wickedness of any family or people that their ancestors were famed for virtue and probity; and commonly those that thus degenerate prove the most wicked of all men. Corruptio optimi est pessima - That which was originally the best becomes when corrupted the worst, Luk 11:26; Ecc 3:16; See Jer 22:15-17. The degeneracy of Jerusalem is illustrated, (1.) By similitudes (Isa 1:22): Thy silver has become dross. This degeneracy of the magistrates, whose character is the reverse of that of their predecessors, is a great a reproach and injury to the kingdom as the debasing of their coin would be and the turning of their silver into dross. Righteous princes and righteous cities are as silver for the treasury, but unrighteous ones are as dross for the dunghill. How has the gold become dim! Lam 4:1. Thy wine is mixed with water, and so has become flat and sour. Some understand both these literally: the wine they sold was adulterated, it was half water; the money they paid was counterfeit, and so they cheated all they dealt with. But it is rather to be taken figuratively: justice was perverted by their princes, and religion and the word of God were sophisticated by their priests, and made to serve what turn they pleased. Dross may shine like silver, and the wine that is mixed with water may retain the colour of wine, but neither is worth any thing. Thus they retained a show and pretence of virtue and justice, but had no true sense of either. (2.) By some instances (Isa 1:23): "Thy princes, that should keep others in their allegiance to God and subjection to his law, are themselves rebellious, and set God and his law at defiance." Those that should restrain thieves (proud and rich oppressors, those worst of robbers, and those that designedly cheat their creditors, who are no better), are themselves companions of thieves, connive at them, do as they do, and with greater security and success, because they are princes, and have power in their hands; they share with the thieves they protect in their unlawful gain (Psa 50:18) and cast in their lot among them, Pro 1:13, Pro 1:14. [1.] The profit of their places is all their aim, to make the best hand they can of them, right or wrong. They love gifts, and follow after rewards; they set their hearts upon their salary, the fees and perquisites of their offices, and are greedy of them, and never think they can get enough; nay, they will do any thing, though ever so contrary to law and justice, for a gift in secret. Presents and gratuities will blind their eyes at any time, and make them pervert judgment. These they love and are eager in the pursuit of, Hos 4:18. [2.] The duty of their places is none of their care. They ought to protect those that are injured, and take cognizance of the appeals made to them; why else were they preferred? But they judge not the fatherless, take no care to guard the orphans, nor does the cause of the widow come unto them, because the poor widow has no bribe to give, with which to make way for her and to bring her cause on. Those will have a great deal to answer for who, when they should be the patrons of the oppressed, are their greatest oppressors.
II. A resolution is taken up to redress these grievances (Isa 1:24): Therefore saith the Lord, the Lord of hosts, the Mighty One of Israel - who has power to make good what he says, who has hosts at command for the executing of his purposes, and whose power is engaged for his Israel - Ah! I will ease me of my adversaries. Observe,
1.Wicked people, especially wicked rulers that are cruel and oppressive, are God's enemies, his adversaries, and shall so be accounted and so dealt with. If the holy seed corrupt themselves, they are the foes of his own house.
2.They are a burden to the God of heaven, which is implied in his easing himself of them. The Mighty One of Israel, that can bear any thing, nay, that upholds all things, complains of his being wearied with men's iniquities, Isa 43:24. Amo 2:13.
3.God will find out a time and a way to ease himself of this burden, by avenging himself on those that thus bear hard upon his patience. He here speaks as one triumphing in the foresight of it: Ah. I will ease me. He will ease the earth of the burden under which it groans (Rom 8:21, Rom 8:22), will ease his own name of the reproaches with which it is loaded. He will be eased of his adversaries, by taking vengeance on his enemies; he will spue them out of his mouth, and so be eased of them, Rev 3:16. He speaks with pleasure of the day of vengeance being in his heart, Isa 63:4. If God's professing people conform not to his image, as the Holy One of Israel (Isa 1:4), they shall feel the weight of his hand as the Mighty One of Israel: his power, which was wont to be engaged for them, shall be armed against them. In two ways God will ease himself of this grievance: -
(1.)By reforming his church, and restoring good judges in the room of those corrupt ones. Though the church has a great deal of dross in it, yet it shall not be thrown away, but refined (Isa 1:25): "I will purely purge away thy dross. I will amend what is amiss. Vice and profaneness shall be suppressed and put out of countenance, oppressors displaced, and deprived of their power to do mischief." When things are ever so bad God can set them to rights, and bring about a complete reformation; when he begins he will make an end, will take away all the tin. Observe, [1.] The reformation of a people is God's own work, and, if ever it be done, it is he that brings it about: "I will turn my hand upon thee; I will do that for the reviving of religion which I did at first for the planting of it." He can do it easily, with the turn of his hand; but he does it effectually, for what opposition can stand before the arm of the Lord revealed? [2.] He does it by blessing them with good magistrates and good ministers of state (Isa 1:26): "I will restore thy judges as at the first, to put the laws in execution against evil-doers, and thy counsellors, to transact public affairs, as at the beginning," either the same persons that had been turned out or others of the same character. [3.] He does it by restoring judgment and righteousness among them (Isa 1:27), by planting in men's minds principles of justice and governing their lives by those principles. Men may do much by external restraints; but God does it effectually by the influences of his Spirit, as a Spirit of judgment, Isa 4:4; Isa 28:6. See Psa 85:10, Psa 85:11. [4.] The reformation of a people will be the redemption of them and their converts, for sin is the worst captivity, the worst slavery, and the great and eternal redemption is that by which Israel is redeemed from all his iniquities (Psa 130:8), and the blessed Redeemer is he that turns away ungodliness from Jacob (Rom 11:26), and saves his people from their sins, Mat 1:21. All the redeemed of the Lord shall be converts, and their conversion is their redemption: "Her converts, or those that return of her (so the margin), shall be redeemed with righteousness." God works deliverance for us by preparing us for it with judgment and righteousness. [5.] The reviving of a people's virtues is the restoring of their honour: Afterwards thou shalt be called the city of righteousness, the faithful city; that is, First, "Thou shalt be so;" the reforming of the magistracy is a good step towards the reforming of the city and the country too. Secondly, "Thou shalt have the praise of being so;" and a greater praise there cannot be to any city than to be called the city of righteousness, and to retrieve the ancient honour which was lost when the faithful city became a harlot, Isa 1:21.
(2.)By cutting off those that hate to be reformed, that they may not remain either as snares or as scandals to the faithful city. [1.] it is an utter ruin that is here threatened. They shall be destroyed and consumed, and not chastened and corrected only. The extirpation of them will be necessary to the redemption of Zion. [2.] It is a universal ruin, which will involve the transgressors and the sinners together, that is, the openly profane that have quite cast of all religion, and the hypocrites that live wicked lives under the cloak of a religious profession - they shall both be destroyed together, for they are both alike an abomination to God, both those that contradict religion and those that contradict themselves in their pretensions to it. And those that forsake the Lord, to whom they had formerly joined themselves, shall be consumed, as the water in the conduit-pipe is soon consumed when it is cut off from the fountain. [3.] It is an inevitable ruin; there is no escaping it. First, Their idols shall not be able to help them, the oaks which they have desired, and the gardens which they have chosen; that is, the images, the dunghill-gods, which they had worshipped in their groves and under the green trees, which they were fond of and wedded to, for which they forsook the true God, and which they worshipped privately in their own garden even when idolatry was publicly discountenanced. "This was the practice of the transgressors and the sinners; but they shall be ashamed of it, not with a show of repentance, but of despair, Isa 1:29. They shall have cause to be ashamed of their idols; for, after all the court they have made to them, they shall find no benefit by them; but the idols themselves shall go into captivity," Isa 46:1, Isa 46:2. Note, Those that make creatures their confidence are but preparing confusion for themselves. You were fond of the oaks and the gardens, but you yourselves shall be, 1. "Like an oak without leaves, withered and blasted, and stripped of all its ornaments." Justly do those wear no leaves that bear no fruit; as the fig-tree that Christ cursed. 2. "Like a garden without water, that is neither rained upon nor watered with the foot (Deu 11:10), that had no fountain (Sol 4:15), and consequently is parched, and all the fruits of it gone to decay." Thus shall those be that trust in idols, or in an arm of flesh, Jer 17:5, Jer 17:6. But those that trust in God never find him as a wilderness, or as waters that fail, Jer 2:31. Secondly, They shall not be able to help themselves (Isa 1:31): "Even the strong man shall be as tow not only soon broken and pulled to pieces, but easily catching fire; and his work (so the margin reads it), that by which he hopes to fortify and secure himself, shall be as a spark to his own tow, shall set him on fire, and he and his work shall burn together. His counsels shall be his ruin; his own skin kindles the fire of God's wrath, which shall burn to the lowest hell, and none shall quench it." When the sinner has made himself as tow and stubble, and God makes himself to him as a consuming fore, what can prevent the utter ruin of the sinner?
Now all this is applicable, 1. To the blessed work of reformation which was wrought in Hezekiah's time after the abominable corruptions of the reign of Ahaz. Then good men came to be preferred, and the faces of the wicked were filled with shame. 2. To their return out of their captivity in Babylon, which had thoroughly cured them of idolatry. 3. To the gospel-kingdom and the pouring out of the Spirit, by which the New Testament church should be made a new Jerusalem, a city of righteousness. 4. To the second coming of Christ, when he shall thoroughly purge his floor, his field, shall gather the wheat into his barn, into his garner, and burn the chaff, the tares, with unquenchable fire.
For we will not mimic the false prophets who say that most things have been done by them. This is the meaning of “to corrupt,” when someone dilutes the wine, or when someone sells something which ought to be given away freely. He seems to me to be both taunting them regarding money and hinting at the fact that they have mingled the things of God with their own things, as I have said. This is the accusation of Isaiah, who says, “Your wine merchants mingle wine with water.” Even if this statement were about wine, one would not sin to say it of doctrine as well. He says, “We do not do this, but we offer to you what we have been given, pouring out the undiluted word.”
(Verse 25) And I will turn my hand against you; and I will thoroughly purge away your dross and take away all your alloy. Regarding the dross, which Symmachus interpreted as 'στέμφυλα' (clusters of grapes), Aquila as 'γιγαρτῶδες' (bunch of grapes), and Theodotion as 'acinum uvae' (grape kernel), the Septuagint alone, translating more the sense than the words, understood it as 'unbelievers' or 'disobedient ones'. For after he had said, 'Your silver has become dross,' he now uses a metaphor, that he may stretch out his hand over it, that is, extend his hand for punishment and cleansing, and purge away all the filth and vices of sins, so that, the alloy being separated, pure silver may remain, which cannot be made without fire, through which he signifies that they will suffer torments. We also read in Malachi about the Lord: He will come forth like a flame of a smelting furnace, and like the herb of the fullers, and He will sit refining and purifying like silver and gold; and He will purify the sons of Levi (Malachi 3:2-3), so that after they have been cleansed, it may be said of them: And they shall be the Lord's offering in righteousness. Ezekiel also says that the whole house of Israel is mixed with brass, iron, lead, and tin, and needs to be purified; so that after it has been purified, it may recognize that He is the Lord (Ezekiel 22:18). But also in the Gospel under another metaphor the same meaning is shown: Whose fan is in his hand, and he will thoroughly cleanse his floor and gather his wheat into the barn; but the chaff he will burn with unquenchable fire. (Matthew 3:12).
(Verse 19, 26.) If you are willing and obedient, you will eat the good of the land; but if you refuse and rebel, you shall be devoured by the sword; for the mouth of the Lord has spoken. Free will is preserved, so that on either side, not by the prejudice of God, but by the merits of each individual, there may be either punishment or reward. By the good of the land, I believe those things are meant that we read of in the psalm: I believe that I shall see the goodness of the Lord in the land of the living (Psalm 27:13); and: Blessed are the meek, for they shall inherit the earth (Matthew 5:3). Certainly, because he spoke to the Jews, who were not yet able to understand spiritual things, he promises them the goods of the present age, so that they may at least be enticed by the present things and do what is commanded. And because they did not want to listen, but on the contrary provoked the Holy One of Israel to anger, therefore the sword devoured them, that is, the Roman army destroyed them. And he says that all these things will happen because the mouth of the Lord has spoken. His judgment, with the sins of men remaining, cannot be changed.
[This concerns] the faithful city of Zion, which later became a harlot. In place of the righteous, or righteousness, murderers dwelled within her. The Lord, therefore, turned his hand and purged her of impurities and removed all her alloy and restored her judges as at the beginning, and her counselors as of old. The prior judges were Moses and Joshua the son of Nun, and others from whom a book of sacred Scripture received its name. Later, David and other righteous kings were added. He will restore, therefore, a judge like them, or after the Babylonian captivity, as the Jews desire, Zerubbabel, Ezra, Nehemiah and other leaders who presided over the people until Hyrcanus, whom Herod succeeded as king. In any event, the apostles and those who believed through the apostles were established as more trustworthy and upright leaders of the church, in keeping with what we said at the beginning of this vision, namely, that both the threat and the promise pertain to the time of the Lord’s passion and to the faith that formed the church after his passion. “Afterward you will be called the city of the righteous, a faithful city.” This prophetic word clearly embraces the church, composed of both the Jews and the Gentiles who would come to believe in the Lord. It is also the city of the righteous, that is, of the Lord our Savior, for she herself is called righteous about whom it was said, “A city set on a hill cannot be hidden.” Thus, calling her faithful, or metropolim according to the Septuagint, it shows that those who will believe in the Lord must also be known by these titles.
This occurs for the sake of cleansing, however, when he humbles his righteous ones for their small and as it were insignificant sins or because of their proud purity, giving them over to various trials in order to purge away now all the unclean thoughts … which he sees have collected in their inmost being, and in order to submit them like pure gold to the judgment to come, permitting nothing to remain in them that the searching fire of judgment might afterwards find to purge with penal torment.

SUMMARY
Isaiah 1:25 powerfully declares God's sovereign and purposeful intent to purify His covenant people, Judah and Jerusalem. Using the vivid and culturally resonant metaphor of a refiner separating precious metal from worthless impurities, the verse underscores God's unwavering commitment to a thorough and transformative cleansing process. This divine intervention, though potentially intense and painful, is not aimed at destruction but at the restoration of His people to a state of righteousness, holiness, and genuine fellowship, thereby preparing them to fulfill their divine purpose.
CONTEXT
EXPOSITION AND ANALYSIS
Key Word Analysis
Verse Breakdown
Literary Devices
Isaiah 1:25 is exceptionally rich in Metaphor, primarily employing the vivid imagery of a metal refiner. God is depicted as the divine metallurgist, actively engaged in a process of purification, while His people (Judah/Jerusalem) are the raw metal. The impurities of "dross" and "tin" powerfully represent the nation's pervasive sins, idolatry, and social injustice. This central metaphor conveys that God's judgment is not arbitrary destruction but a purposeful, intense process designed to purify and restore. The phrase "turn my hand upon thee" utilizes Personification, attributing a human action (turning a hand) to God, thereby emphasizing His active, personal involvement and sovereign control over this refining process. Furthermore, the verse exhibits clear Parallelism in its structure, specifically Synonymous Parallelism, where the clauses "purely purge away thy dross" and "take away all thy tin" convey a similar idea of thorough cleansing through different but closely related terms. This repetition serves to reinforce the completeness, certainty, and unsparing nature of God's purifying work.
THEOLOGICAL AND THEMATIC CONNECTIONS
Isaiah 1:25 powerfully articulates the profound theological truth that God's judgment is often redemptive, serving as a divine means to purify His people rather than merely to destroy them. This verse highlights God's unwavering commitment to holiness, both His own inherent character and the holiness He desires for His covenant people. He is not content with a superficial faith or a compromised people; His perfect love and justice compel Him to confront and remove the impurities that hinder true relationship and effective witness. The refining process, though painful and intensely demanding, stands as a testament to His faithfulness and His ultimate goal of restoring His people to a state of righteousness and utility, making them fit for His purposes and for genuine, unhindered fellowship with Him. This theme resonates throughout Scripture, demonstrating God's consistent character as the one who disciplines those He loves for their ultimate good and sanctification, always with a view toward restoration.
REFLECTION AND APPLICATION
Isaiah 1:25 offers profound comfort and a significant challenge for believers today. It assures us that when God allows or directly brings difficulties, trials, or even discipline into our lives, His ultimate aim is not punitive destruction but loving purification and sanctification. These experiences are God's refining fire, meticulously designed to burn away the "dross" of our sins, our self-reliance, our unhealthy attachments, our ungodly attitudes, and anything that hinders our walk with Him, leaving behind a purer, more Christ-like character. Embracing this refining process requires a posture of humility and deep trust, acknowledging that the pain of purging is often a necessary component for genuine spiritual growth and maturity. We are called to submit to God's sovereign hand, believing that His wisdom is perfect and His love is unwavering, even when the heat of the process feels intense. Just as purified metal becomes more valuable and useful for its intended purpose, a heart cleansed by God's refining work is more capable of bearing His image, reflecting His glory, and fulfilling His purposes in the world. This verse instills profound hope that God is actively and lovingly working to make us holy, conforming us ever more closely to the image of His Son.
Questions for Reflection
FAQ
Does God's refining process always involve suffering?
Answer: While not all suffering is direct divine discipline, the biblical metaphor of refining inherently implies intense heat, which can indeed be painful. The process of purging "dross" and "tin" from metal requires high temperatures and often violent agitation. Similarly, God's work of purifying His people can involve challenging circumstances, trials, and discipline that expose and remove sin, pride, self-reliance, and other impurities. This is not for God's pleasure in our pain, but for our ultimate good and holiness, as clearly articulated in Hebrews 12:10, where God chastens us "for our profit, that we might be partakers of his holiness." The goal is always purification, leading to greater spiritual strength, purity, and conformity to Christ's image.
How can I cooperate with God's refining work in my life?
Answer: Cooperating with God's refining work involves several key steps that demonstrate a humble and trusting heart. First, cultivate a posture of humility and repentance, acknowledging your sin and areas where you need to grow, as exhorted in James 4:10. Second, trust in God's perfect wisdom and unfailing love, even when the process is difficult or painful, remembering that He works all things for the good of those who love Him and are called according to His purpose Romans 8:28. Third, actively pursue holiness through diligent obedience to His Word, consistent prayer, and complete reliance on the Holy Spirit, allowing Him to transform you from the inside out Philippians 2:12-13. Finally, embrace the trials and challenges as opportunities for profound spiritual growth, knowing that perseverance produces character, and character, hope Romans 5:3-4.
CHRIST-CENTERED FULFILLMENT
Isaiah 1:25, with its powerful imagery of divine refining, finds its ultimate and most profound fulfillment in the person and redemptive work of Jesus Christ. While the immediate context speaks to God's judgment and purification of Old Testament Israel, the New Testament reveals that Christ is the ultimate Refiner and the singular means by which true spiritual purity is achieved for all humanity. His atoning sacrifice on the cross is the supreme act of "purging away" sin, not with literal fire, but with His own precious blood, as Hebrews 9:22 teaches that "without shedding of blood there is no remission." Through Christ's finished work, believers are declared righteous (justification) and are progressively sanctified by the Holy Spirit. The "dross" and "tin" of sin, which alienated humanity from a holy God, were decisively taken away by the Lamb of God who takes away the sin of the world. Furthermore, Christ's ongoing work through His Spirit continues to refine His church, His bride, preparing her to be presented to Himself as a "radiant church, without stain or wrinkle or any other blemish, but holy and blameless" Ephesians 5:27. Thus, the promise of purification in Isaiah is not merely a historical event for Israel but a spiritual reality for all who are in Christ, who are continually being transformed into His likeness "from glory to glory" by the Spirit of the Lord 2 Corinthians 3:18.
