Isaiah 59:5 Commentary: Sin as Poison and Futility

Isaiah 59 opens with a sharp corrective: God’s hand is not too short to save, nor His ear too dull to hear; the people’s iniquities have caused the separation (vv. 1, 2). Verses 3, 4 catalogue specific sins, hands defiled with blood, lips speaking lies, no one pursuing justice. Against that backdrop, verse 5 draws two metaphors that would strike any ancient audience. The first, hatching vipers’ eggs, would evoke the life cycle of venomous snakes such as the adder (צפעון, tzif‘oni) or the Egyptian cobra. In the ancient Near East, finding a nest of reptile eggs meant either crushing them (a wise act of prevention) or leaving them to hatch, choosing to foster the brood was tantamount to nurturing destruction. “Cockatrice” in older translations (KJV, Geneva) refers to a legendary basilisk, but the Hebrew points to a real, deadly serpent. The second image, weaving a spider’s web (עכביש, akkavish), contrasts sharply with the careful, strong weaving expected for garments. Spiders were already proverbial for fragility in Job 8:14. The web cannot cover or protect. The verbs are iterative: “they hatch … they weave”, these are habitual actions. Together, the metaphors accuse Israel of actively cultivating evil and spinning schemes that are both toxic and useless. The crushing (or “pressing”) of the egg releases a viper (אפעה, ef‘eh): even when wickedness is confronted, it strikes back. The passage thus locates sin’s tragedy in two dimensions: what sin produces (poison) and what it cannot produce (covering, righteousness). This double failure explains the later confession in vv. 9, 15 that justice is far from them.

The supplied commentaries note no significant textual variants for Isaiah 59:5 beyond translation differences of the animal names (cockatrice, adder, viper). The Cambridge Bible observes that Duhm and Cheyne regarded vv. 5, 8 as possibly a quotation from a lost psalm or proverbs, but this is a literary-critical observation, not a textual one. The Masoretic text reads consistently across all witnesses used by the cited commentators. The forms of the verbs (בקע, perfect/iterative, ארג, imperfect habitual) are well-attested.

Isaiah 59:5 has been most influential through its echo in the New Testament, where John the Baptist and Jesus both call opponents “offspring of vipers” (Matthew 3:7; 12:34). The figure of hatching viper eggs entered early Christian catechesis as a warning against nurturing sin. In the Reformation, both Luther and Calvin used the spider’s web image to argue that human works cannot justify a person before God. Matthew Henry (1710) amplifies the futility theme: “They trust in vanity, and speak lies.” Wesley’s Notes (1754) treat the verse as a proverbial summary of evil design and ultimate failure. The verse has also featured in hymns that contrast human sin with God’s covering righteousness, though no single hymn is uniquely associated with this text.

Three-point outline

1. Sin is actively cultivated, not merely suffered. “They hatch … they weave.” The wicked do not drift into evil; they tend it like a nest. Preaching point: examine the habits we nurture, what are we hatching in our hearts?
2. Sin is both deadly and futile. The eggs bring death; the webs are useless. No one is covered by the works of the flesh. Preaching point: moral effort cannot earn salvation or hide us from God. Only Christ’s righteousness covers.
3. Sin’s consequences cannot be avoided. Eating the eggs kills; crushing them releases a viper. There is no neutral stance. Preaching point: we cannot dabble with evil or assume we can manage it. The only safety is in God’s mercy through repentance.

Five-point outline

1. The root: sin’s origin in broken relationship with God (vv. 1, 2).
2. The reach: sin pollutes every part of life (vv. 3, 4).
3. The reproductive power: sin spawns more sin (v. 5a, hatching eggs).
4. The failure: sin cannot provide what it promises (v. 5b, 6, web cannot cover).
5. The remedy: confession and divine intervention (vv. 16, 20, God’s own arm brings salvation).

Illustration hooks

• A gardener who finds a nest of venomous snake eggs, does he destroy them or keep them warm? The choice illustrates deliberate cultivation of sin vs. immediate repentance.
• A spider’s web in a doorway, it looks delicate and beautiful, but it cannot stop a wind or block an intruder. Our self-made righteousness is like that web.
• The phrase “that which is crushed breaks out into a viper”, consider a person who gently opposes a common sin among friends, only to discover that the sin strikes back with anger or resentment. Sin lashes out when exposed.

Questions your congregation is asking

• “Why does God seem distant when I pray?”, The chapter begins with that very question. Sin, not God, creates the separation.
• “I’m trying to be a better person, isn’t that enough?”, The spider’s web metaphor says: our best efforts cannot cover or save. We need God’s covering.
• “What’s so dangerous about small, secret sins?”, Because they are like hatched vipers: small eggs now, deadly serpents later.

This passage forces us to take sin seriously, not as a list of mistakes, but as something we actively cultivate. Yet the chapter does not leave us without hope; by verse 20 the Redeemer comes to Zion. Use these questions to explore the nature of sin and the only true covering for it.

Discussion questions

1. Read Isaiah 59:1, 5. Why does the prophet begin with God’s ability and then immediately turn to the people’s sin? What is his strategy?
2. The people “hatch adders’ eggs” and “weave the spider’s web.” In what ways do we, even unintentionally, support or nurture evil in our own lives?
3. The web cannot become a garment (v. 6). How does this statement challenge the belief that our good deeds can cover our sins or earn God’s favor?
4. Verse 5 says that eating the eggs (participating in the schemes) leads to death, and crushing them releases a viper. What does this teach us about the danger of trying to confront or “manage” sin on our own?
5. How does the New Testament language about “offspring of vipers” (Matthew 3:7; 12:34) draw from this Old Testament image, and what does it add to Jesus’ call to repentance?
6. What kind of “web” might we be weaving today, in our speech, our work, or our relationships, that looks good but cannot stand before God?
7. Verse 6 says their “works” will not cover them. The chapter later promises that God Himself will bring salvation (v. 16, 20). How does this shift the focus from human effort to divine rescue?
