The idea of Sheol ("שׁאול") or a state of nothingness was shared among Babylonian and Israelite beliefs. "Sheol, as it was called by the ancient Israelites, is the land of no return, lying below the cosmic ocean, to which all, the mighty and the weak, travel in the ghostly form they assume after death, known as Rephaim. There the dead have no experience of either joy or pain, perceiving no light, feeling no movement." Obayashi alludes that the Israelites were satisfied with such a shadowy realm of afterlife because they were more deeply concerned with survival.
