Charles Ellicott Commentary Job 34:9

"For he hath said, It profiteth a man nothing That he should delight himself with God." — Job 34:9 (ASV)

It profits a man nothing. Compare what Job had said (Job 9:20–22; Job 9:30–31; Job 10:6–7; Job 10:14–15).

Eliphaz had virtually said the same thing, though the form in which he phrased it was the opposite of this . He had represented it as a matter of indifference to God whether man was righteous or not, which was, of course, to undermine the foundations of all morality. For if God does not care whether man is righteous or not, it certainly cannot profit man to be righteous.

On the other hand, Eliphaz had formally stated the opposite doctrine (Job 22:21).
