Adam Clarke on Job 9:15

Though I were righteous - Though clear of all the crimes, public and secret, of which you accuse me, yet I would not dare to stand before his immaculate holiness. Man's holiness may profit man, but in the sight of the infinite purity of God it is nothing. Thus sung an eminent poet: - "I loathe myself when God I see,And into nothing fall;

Content that thou exalted be,And Christ be all in all."

I would make supplication to my Judge - Though not conscious of any sin, I should not think myself thereby justified; but would, from a conviction of the exceeding breadth of the commandment, and the limited nature of my own perfection, cry out, "Cleanse thou me from secret faults!"
