Scripture:Nature of Sheol/Hades
Comment: Hades (Sheol in the Old Testament) is sometimes translated or interpreted as "the grave". The Psalmist indeed refers to "Sheol" and then to "the pit" (Psa 30:3). Some assert that the Psalmist is speaking of the grave where the fleshly body decays at death. The Psalmist, however, speaks of Sheol as a place for the "soul" and nobody's soul has ever been buried in a grave. Another translation of Sheol is "hell" which confuses Sheol with Gehenna, the eternal abode of the wicked. Because of these problems some translators prefer to merely transliterate, thus they put the words Sheol and Hades.
