tn Heb “And if a man strikes any soul [נֶפֶשׁ, nefesh] of mankind.” The idiom seems to derive from the idea of striking a fatal blow to the very “life” (literally, “soul”) of a human being, not just landing a blow on their body (HALOT 698 s.v. נכה hif.2). On the difficult of the meaning and significance of the term נֶפֶשׁ see the notes on Lev 17:10-11.
