ou si, par inimitié, il lui porte un coup avec la main et qu’il meure, l’homicide doit être mis à mort, c’est un assassin; le vengeur du sang devra le tuer sitôt qu’il le rencontre.

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.
