The Greek word Hades has its equivalent in Hebrews as Sheol and it appears Forty two times in the new testament; it refers to the temporary unseen abode the departed soul/spirit. It is described in the Bible as a place beneath the earth (Prov.15:24; Job 10:22).
Hades is different from the grave (Heb. Qeber). In the old testament, the Hebrew word Sheol appears Sixty five times and it was used to denote the abode for both the righteous and the wicked after death. The geographical location of Hades is unspecified in the Bible.
