For the moth shall eat them up like a garment and the worm shall eat them like wool: but my righteousness shall be for ever and my salvation from generation to generation.Isaiah 51:8 Explainer ## Introduction - In Plain Language: Some things people build—power, wealth, reputation—will waste away like clothes eaten by insects; but God's justice and rescue last forever and keep being passed down through the generations. - Big idea: Human strength and pride are temporary; God’s righteousness and salvation are eternal and reliable. - Key points: - The moth-and-worm image shows how quickly outward things decay. - God’s righteousness is presented as lasting, not subject to decay. - Salvation is not just for one moment but is carried from generation to generation. ## Context - Where this verse fits in: Isaiah 51 is part of the section often called “Second Isaiah” (chapters 40–55), a block of comforting material aimed at people who have experienced exile and loss. This verse contrasts the fleeting nature of human things with the permanence of God’s saving work. - Story timeline: Likely addressed during or shortly after the Babylonian exile (6th century BC). The speaker is God (through the prophet Isaiah), and the primary audience is the exiled Israelites and the faithful remnant who need encouragement. - Surrounding passage: The nearby verses call the people to look up and remember God’s ways (v.6–7), warn that the wicked will fade, and then move into a hopeful summons to awaken and trust God’s power to redeem and bring comfort (vv.9–11). Verses before remind the faithful to not fear human scorn; verses after celebrate God’s vindication and the return of joy to Zion. ## Explanation - Quick take: Isaiah uses the common image of clothes eaten by moths and wool devoured by worms to say: what people rely on for security can quickly be destroyed—God’s righteousness and saving power, by contrast, are permanent and will bless generations. - In Depth: This short verse is a compact contrast. The first half uses vivid, everyday images—moths eating garments, worms devouring wool—to communicate total ruin. Clothing and wool were valuable and visible signs of status and security in the ancient world; seeing them eaten away would be shameful and destructive. The second half flips the scene: whatever is temporary and decaying is set against God’s “righteousness” (Hebrew tsedaqah) and “salvation” (yeshu'ah), which are spoken of as ongoing realities that endure through generations. The rhetorical point is twofold: first, human power, possessions, and even the schemes of those who oppose God’s people are fragile and will be consumed; second, God’s saving action and just character are stable realities that outlast empires and human lifetimes. For people who had lost nation, home, and security, this was a direct word of hope: trust God’s long-lasting salvation rather than short-lived human fixes. ## Key Words - Tola'at (תּוֹלַעַת) — often translated “worm” or “moth”; an insect image for corruption and slow destruction. - Tsedaqah (צְדָקָה) — “righteousness”; here it can mean God’s righteous character and/or His acts of vindication and justice. - Yeshu'ah (יְשׁוּעָה) — “salvation”; deliverance that is both present and passed on “from generation to generation.” - Ledor va-dor (לְדוֹר וָדוֹר) — “from generation to generation”; an idiom emphasizing continuity and covenant faithfulness over time. ## Background - Textile imagery: In the ancient Near East, wool and garments were everyday necessities and often tied to economic and social standing. Moths and worms eating textiles is a vivid way to describe total loss and shame. - Covenant promise theme: Phrases like “from generation to generation” echo covenant language elsewhere in Scripture, emphasizing God’s long-term commitment to His people. - Literary setting: Isaiah 51 follows themes of comfort, the reversal of fortunes, and God’s power to redeem—common in the exile-era prophecies that reassure a displaced people that God has not forgotten them. ## Theology - Theological insights in plain language: - God’s attributes (righteousness and salvation) are enduring; they do not decay like human achievements. - The verse reassures the faithful that God’s saving work is not a one-time event but part of a continuous, intergenerational care. - It warns against placing ultimate trust in temporal things—wealth, status, or oppressive power—which are transient. ## Application To Your Life - For workers: Don’t base your identity only on job titles, income, or career success—those can be lost. Cultivate character and trust in God’s lasting justice. - For parents: Teach children about values and faith that outlast possessions; invest more in spiritual and moral heritage than in material comfort alone. - For leaders: Remember that policies, reputations, and short-term gains fade—build systems of justice and care that reflect God’s enduring righteousness. - For seekers and the hurting: This verse offers hope that what’s broken now won’t be the final word; God’s saving power endures beyond present suffering. - Reflection questions: - What are the “garments” in my life I’m tempted to trust that could be eaten away? - How am I investing in things that will matter to the next generation? - In what ways can I align my life more with God’s enduring righteousness? - Short prayer: Lord, help me not to trust in things that decay; teach me to live by your enduring righteousness and to pass on your salvation to those who come after me. ## Translation Comparison - King James Version (KJV): “For the moth shall eat them up like a garment, and the worm shall eat them like wool: but my righteousness shall be for ever, and my salvation from generation to generation.” - New International Version (NIV): “Moths will eat them up like a garment; worms will devour them like wool. But my righteousness will last forever, my salvation through all generations.” - English Standard Version (ESV): “For the moth will eat them up like a garment, and the worm will eat them like wool; but my righteousness will be forever, and my salvation to all generations.” - New Living Translation (NLT): “Moths will eat them and destroy them, like a moth that devours clothing. Worms will eat them and turn them into dust, like wool that is eaten away. But my justice will last forever, and my salvation will endure from one generation to the next.” - Note on why differences matter: Translations differ in tone and emphasis. Words like “righteousness,” “justice,” or “my righteousness” can highlight either God’s character or his actions to set things right. “From generation to generation” vs. “to all generations” is mostly stylistic, but it affects how explicitly the verse sounds like a covenant promise handed down through time. The underlying Hebrew stresses both the permanence of God’s saving act and its intergenerational reach. ## FAQs - Q: Who are “them” in this verse? A: The immediate context points to those who oppose or oppress God’s people—the proud, the unjust, or idols and the powers people trust instead of God. Earlier and later verses in the chapter contrast the fading power of the wicked with God’s lasting deliverance for the faithful. Practically, “them” can mean any temporary source of security (wealth, political power, ideology, false gods) that people trust in place of God. The point is not simply judgment for its own sake but to reassure the faithful that the sources of their suffering will not endure while God’s justice and salvation will. - Q: Does this mean God’s righteousness is only about punishment for the wicked? A: Not only. “Righteousness” here carries multiple shades: God’s moral character (He is just and true), God’s acts of vindication (He will set matters right), and God’s faithful covenant behavior toward His people. The verse contrasts transient destruction with God’s permanent saving justice—so it includes judgment but centers mainly on God’s enduring commitment to rescue and restore. For the faithful, it’s comfort; for oppressors, it’s a warning. ## Cross References - Isaiah 54:17 — “No weapon formed against you shall prosper” (connection: God’s protective deliverance continues). - Psalm 119:89 — “Your word, LORD, is eternal” (connection: God’s truth endures beyond human change). - Matthew 6:19–20 — “Do not store up for yourselves treasures on earth… but store up for yourselves treasures in heaven” (connection: what decays versus what endures). - 1 Peter 1:25 — “but the word of the Lord endures forever” (connection: permanence of God’s word and salvation). ## Deeper Study - Commentary synthesis (high-level): Most commentators read Isaiah 51:8 as a consoling proverb aimed at people who have experienced loss: human power and possessions are temporary and will be consumed, but God’s righteousness and deliverance are timeless. The verse functions both as a warning to oppressors and as a promise to the vulnerable. It ties into broader Isaiah themes: God’s covenant faithfulness, future vindication, and the reversal of fortunes for the oppressed. - Group study bullets: - Read the verse aloud and ask group members what images stand out—why do moths and worms feel powerful metaphors? - Identify who might be represented by “them” in your context—systems, behaviors, beliefs? - Discuss practical ways to prioritize God’s righteousness in personal, family, and community life. - Pray for one area where the group trusts a transient “garment” and ask God to redirect that trust to His saving character. ## Related verses (to compare and contrast — and why) - Isaiah 45:17 — “Israel is saved by the LORD with an everlasting salvation; you shall not be put to shame or confounded to all eternity.” Why: Both stress the enduring nature of God’s salvation. - Matthew 6:19–21 — about treasures that decay vs. heavenly treasures. Why: Jesus picks up the same contrast between what perishes and what endures. - Psalm 119:89 / 1 Peter 1:25 — “Your word is forever.” Why: These verses connect God’s unchanging word to the permanence of His saving acts and character, similar to Isaiah’s emphasis that God’s righteousness endures. ## Talk to the Bible Try the “Talk to the Bible” feature to dig deeper.
