Here "the sword" refers to a person who kills someone with sword. Also, killing someone with a sword is spoken of as if the sword were "eating" the people. Alternate translation: "for one man can be killed by a sword the same as another man" or "for any man can die in battle" (See: [[rc://en/ta/man/jit/figs-metonymy]] and [[rc://en/ta/man/jit/figs-metaphor]])
