Hades

That which is out of sight, a Greek word used to denote the state or place of the dead. All the dead alike go into this place. To be buried, to go down to the grave, to descend into hades, are equivalent expressions. In the LXX. this word is the usual rendering of the Hebrew sheol, the common receptacle of the departed (Gen. 42:38; Ps. 139:8; Hos. 13:14; Isa. 14:9).

This term is of comparatively rare occurrence in the Greek New Testament. Our Lord speaks of Capernaum as being "brought down to hell" (hades), i.e., simply to the lowest debasement, (Matt. 11:23). It is contemplated as a kind of kingdom which could never overturn the foundation of Christ's kingdom (16:18), i.e., Christ's church can never die.

In Luke 16:23 it is most distinctly associated with the doom and misery of the lost. In Acts 2:27-31 Peter quotes the LXX. version of Ps. 16:8-11, plainly for the purpose of proving our Lord's resurrection from the dead. David was left in the place of the dead, and his body saw corruption. Not so with Christ. According to ancient prophecy (Ps. 30:3) he was recalled to life.

In Biblical Greek it is associated with Orcus, the infernal regions, a dark and dismal place in the very depths of the earth, the common receptacle of disembodied spirits. Usually Hades is just the abode of the wicked, #Lu 16:23; Re 20:13,14; a very uncomfortable place.
