Exodus 21

Exodus 21 inaugurates the Book of the Covenant, the legal section that runs from chapter 21 through 23:19. It opens with ordinances governing Hebrew slavery — a male slave serves six years and is freed in the seventh without payment; a female slave taken as a concubine retains specific protections against economic degradation if the master takes a second wife. The chapter then addresses capital crimes: striking or cursing a parent, premeditated murder, and kidnapping, all of which carry the death penalty. This is paired with provisions protecting unintentional killers, who may flee to a place of refuge. The arrangement is deliberate — severity and mercy are built into the same framework.

The chapter's most influential section is the talion formula — life for life, eye for eye, tooth for tooth — which has been misread across the centuries as a charter of cruelty but is better understood as a principle of proportionality. Blood feuds, which across the ancient Near East routinely responded to injury with disproportionate retaliation, are replaced by courts adjudicating equivalent compensation. The chapter concludes with the goring ox: an owner whose ox has killed before and been warned bears full liability when the ox kills again. The case has been identified by legal historians as a foundational example of negligence doctrine that flows into Roman law and eventually into modern tort law. The law that arrives at Sinai is already thinking about the structure of civil society.
