The lex talionis is not a mandate for personal vengeance.

Matthew 5:38–42

³⁸Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth:

³⁹But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.

⁴⁰And if any man will sue thee at the law, and take away thy coat, let him have thy cloke also.

⁴¹And whosoever shall compel thee to go a mile, go with him twain.

⁴²Give to him that asketh thee, and from him that would borrow of thee turn not thou away.
