Adam Clarke on Job 23:3

O that I knew where I might find him! - This and the following verse may be read thus: "Who will give me the knowledge of God, that I may find him out? I would come to his establishment; (the place or way in which he has promised to communicate himself); I would exhibit, in detail, my judgment (the cause I wish to be tried) before his face; and my mouth would I fill with convincing or decisive arguments;" arguments drawn from his common method of saving sinners, which I should prove applied fully to my case. Hence the confidence with which he speaks, Job 23:6.
