или вражда поразила его рукой, чтобы он умер; тот, кто поразит его, непременно будет предан смерти: он убийца; кровный мститель убьет убийцу, когда тот его встретит.

Or if he struck him with enmity, why is it stated "by his hand"? Because it states "or if he struck him with an iron tool" etc., "or with a stone" etc., "or with a wooden tool" etc. I only know that if he killed him with those, he is liable. How do I know that if he choked him, strangled him, or kicked him, he is also liable? It is stated "by his hand" from any manner of killing.
