The Phrase Today
"An eye for an eye" is the most commonly cited example of supposedly primitive biblical law, often invoked in arguments about justice, revenge, and proportionality. The phrase appears in discussions of criminal sentencing, international law, retaliation, and personal ethics. Gandhi's famous expansion - "an eye for an eye makes the whole world blind" - has itself become a widely quoted counterstatement.
Biblical Origin
Exodus 21:24 in the King James Bible gives the fullest formulation: "Eye for eye, tooth for tooth, hand for hand, foot for foot." The same principle appears in Leviticus 24:20 and Deuteronomy 19:21. The legal context is crucial: these verses regulate judicial proceedings, not personal vengeance. They establish a ceiling on punishment - courts may not impose a punishment disproportionate to the harm caused. Read in context, lex talionis is not a license for unlimited revenge but a legally enforced limitation on it.
Ancient Legal Background
The Code of Hammurabi (c. 1754 BCE) contains strikingly similar language and predates the Mosaic texts, suggesting that proportionality was a widespread legal norm in the ancient Near East. What distinguished the biblical formulation was its application across class lines: in Hammurabi's code, punishments varied by social status. The Mosaic law applied the same standard to all, which was genuinely egalitarian within its historical context. Ancient Jewish legal practice, moreover, largely interpreted the law monetarily - rabbinical tradition held that "eye for eye" meant fair monetary compensation, not literal extraction.
Jesus and the Antithesis
Matthew 5:38-39 records Jesus's most famous modification: "Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth: But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also." This is one of the six antitheses of the Sermon on the Mount, where Jesus raises the ethical bar beyond legal compliance toward transformative non-retaliation. The tension between Exodus 21 and Matthew 5 has shaped Western ethics, theology, and jurisprudence ever since.
Cross-Linguistic Reach
The Latin lex talionis (law of retaliation) became the technical legal term in Roman law and entered European jurisprudence as a foundational concept. Blackstone's Commentaries and Beccaria's On Crimes and Punishments (1764) - the founding text of modern criminal justice reform - both engaged directly with the principle. International humanitarian law's prohibition on disproportionate force in warfare is a descendant of the same principle, mediated through centuries of just-war theory rooted partly in this Mosaic precedent.
Cultural Usage
The phrase functions in contemporary discourse primarily as a shorthand for retributive justice, often invoked by critics as an example of outdated ethics. The Gandhi quotation, though of uncertain attribution, has given the phrase a dialectical structure - "eye for eye" versus "the whole world blind" - that has become a rhetorical set-piece in discussions of conflict resolution, restorative justice, and peacebuilding. The phrase's biblical provenance lends it authority even in secular arguments: citing scripture, even to contradict its apparent sense, draws on the cultural weight of the text.
