הכתב והקבלה — ויהיו חיי שרה מאה שנה ועשרים שנה ושבע שנים שני חיי שרה

Q — Why does the verse repeat 'חיי שרה' — first 'ויהיו חיי שרה,' then closing 'שני חיי שרה'? Isn't the second occurrence pure redundancy?

A — HaKtav VeHaKabbalah reads 'שני' here not as 'years of' (the construct of שנים) but as the *dual-number form*, like 'שני אנשים' — *two*. A human being is unique in creation in being designed for two simultaneous lives: gashmi (eating, drinking, sleeping, work, commerce) and ruchani (Torah, mitzvot, deveikut). These two must be 'אגודים אחוזים ונצמדים יחד לא יתפרדו לעולם' — fused, never separated. A person whose gashmi life runs on its own track without ruchani purpose is no different from a beast. The verse's testimony about Sarah is therefore: she lived 'שני חיי שרה' — TWO Sarah-lives at once, every gashmi moment serving the ruchani — the actual ideal of human existence. The closing phrase is the eulogy.
