Proportionality, Equality, and Judicial Integrity: Reinterpreting Lex Talionis in Pentateuchal Narratives

The principle of lex talionis, often summed up as “eye for an eye” and “tooth for a tooth,” has been widely seen as a biblical endorsement of retaliation. However, this study re-examines the principle within its legal context in the Pentateuch, focusing on Exodus 21:23-25, Leviticus 24:17-22, and Deuteronomy 19:16-21. Employing a comparative exegetical approach, the paper examined the literary, legal, lexical, and theological aspects of these texts to ascertain how lex talionis functions in various legal frameworks. Findings revealed that this principle does not operate as absolute authorisation for personal vengeance. Rather, Exodus 21:23-25 governs bodily retaliation through proportionality; Leviticus 24:17-22 places reciprocal justice within the realm of community equality, fairness, and a shared legal standard; and Deuteronomy 19:16-21 applies this idea of correspondence to malicious testimony, protecting judicial integrity and ensuring accountability. The paper concluded that these differences mark a significant evolution in Pentateuchal law, where the concept of reciprocity is increasingly shaped by proportionality, equality, institutional authority, due process, and deterrence. Lex talionis therefore emerges not just as a principle of retaliation but as an instrument of regulated justice aimed at curbing excess, protecting individuals, maintaining community order, and upholding the integrity of legal institutions.
