DID YOU KNOW?
The answer
Yes — it's in the Law three times: Exodus 21:24, Leviticus 24:20, and Deuteronomy 19:21. Jesus quotes it in Matthew 5:38 ("You have heard that it was said...") before offering a different way.
Why it’s interesting
The principle, called lex talionis, was meant to cap revenge at the size of the injury, not license it. Many assume it runs against the Bible's ethic, but it's written into the Bible's own law codes.
