Life, Injury, Lex Talionis, Equal Law, and Execution
“Eye for eye” begins as a rule of proportional public justice. Jesus later quotes it in teaching about personal retaliation. Seeing both contexts prevents both Torah and Jesus from being flattened into slogans.
Where this fits in the story: Exodus 21:22–25 — Certain: life/eye/tooth proportionality already appears in covenant law.
Where Scripture takes it next: Matthew 5:38–42 — Certain quotation. Jesus explicitly quotes “eye for eye, tooth for tooth” while teaching disciples not to retaliate.
