욥기 34:14의 미드라쉬

By five names is the soul/nefesh called: nefesh, ru’ach, n’shamah, chayah (living one), y’chidah (unique one). Nefesh – this is the blood . . . Ru’ach – for she rises and falls, [as in:] “Who knows if the ru’ach of human beings goes upward?” [Ec 3:21]. N’shamah – this is the visage/character/ofah. . . Chayah – that all the limbs die and (i.e., unless) she lives in the body. Y’chidah – that all the limbs are two by two [but] she is singular in the body.
