Significance: Peter quotes Proverbs 26:11 as a "true proverb" (to tēs alēthous paroimias): "A dog returns to its own vomit" (kyōn epistrepas epi to idion exerama). He adds a second image not found in Proverbs: "a sow that is washed returns to her wallowing in the mud." Peter applies this wisdom saying to those who, having escaped the defilements of the world through knowledge of Christ, return to their former corruption. The proverb functions analogically: just as a dog's return to its vomit reveals its unchanged nature, so apostates' return to sin reveals that no genuine transformation occurred. The graphic imagery serves Peter's pastoral purpose — warning that mere external exposure to truth without inward renewal leads to a condition "worse than the first" (2:20). The wisdom tradition's observation about the fool's incorrigibility becomes an eschatological warning.
NT Use Pattern: Proverbial — The dog returns to its vomit. A proverbial observation deployed to characterize apostasy — wisdom citation, not prophetic fulfillment.
