Sheol is usually translated by "Hades" in the Septuagint. It is a very general term referring commonly to the parts of the world that lie beneath the surface of the earth (e.g., Num. 16:30-33; Deut. 32:22; Isa. 7:11), including the grave (Isa. 14:11), and to the abode of both the righteous (e.g., Ps. 30:3; Eccl. 9:10) and the wicked (e.g., Ps. 9:17) after death. Other Old Testament texts equate Sheol with "death," as does Paul (1 Cor. 15:55 with Hos. 13:14).

Question:

When the Old Testament speaks of Sheol, who does it see as its inhabitants?
