Job 12:22

He discovereth deep things out of darkness - This may refer either to God's works in the great deep, or to the plots and stratagems of wicked men, conspiracies that were deeply laid, well digested, and about to be produced into existence, when death, whose shadow had hitherto concealed them, is to glut himself with carnage.

He discovereth deep thirsts out of darkness - That is, God discloses truths which are wholly beyond the power of man to discover - truths that seem to be hidden in profound night. This may refer either to the revelation which God was believed to have furnished, or to his power of bringing out the most secret thoughts and purposes, or to his power of predicting future events by bringing them out of darkness to the clear light of day, or to his power of detecting plots, intrigues, and conspiracies.

And bringeth out to light the shadow of death - On the meaning of the word rendered "shadow of death," see the notes at Job 3:5. It here denotes whatever is dark or obscure. It is rather a favorite expression with the author of this poem (see Job 10:22; Job 16:16; Job 24:17; Job 34:22; Job 38:17), though it occurs elsewhere in the Scriptures. The deepest darkness, the obscurest night, are represented by it; and the idea is, that even from the most dark and impenetrable regions God could bring out light and truth. All is naked and open to the mind of God.

12:22 Darkness - The most secret counsels of princes, which are contrived and carried on in the dark.
