Job is the oldest story of the Bible. It predates Moses writings. It delineates and clarifies about who God is in relationship to Man.
"Job contrasts his previous fortune with his present plight, an outcast, mocked and in pain. He protests his innocence, lists the principles he has lived by, and demands that God answer him. Elihu (a character not previously mentioned) intervenes to state that wisdom comes from God, who reveals it through dreams and visions to those who will then declare their knowledge." Via Wikipedia
The verse quote is from Elihu.
