Job 26:6 – Sheol is naked before God, And Abaddon has no covering. — World English
According to Easton’s Dictionary:
Abaddon – destruction, the Hebrew name (equivalent to the Greek Apollyon, i.e., destroyer) of “the angel of the bottomless pit” (Rev. 9:11). It is rendered “destruction” in Job 28:22; 31:12; 26:6; Prov. 15:11; 27:20. In the last three of these passages the Revised Version retains the word “Abaddon.” We may regard this word as a personification of the idea of destruction, or as sheol, the realm of the dead.
Thus rather than finding here any support for the idea that sheol, the realm of death, contains a compartment of conscious torture, it is aligned with destruction. This agrees with other plain statements of scripture. (Ecclesiastes 9:5,10) In the statement of this verse, Job is describing, symbolically, the unlimited wisdom and power of the Creator.
In Job 26:2, Job speaks of how sheol and destruction are naked, or not covered up, to God as to men. While man, of himself, cannot reach into sheol/hades/destruction/the grave to bring the dead back to life, God can.
