Albert Barnes Commentary Job 35:5

"Look unto the heavens, and see; And behold the skies, which are higher than thou." — Job 35:5 (ASV)

Look to the heavens, and see - This is the beginning of the reply that Elihu makes to the sentiment that he understood Job to express, and which Eliphaz had previously proposed to examine. The general object of the reply is to show that God is so great that he cannot be affected by human conduct, and that he has no interest in treating people otherwise than according to their character.

He is so exalted that their conduct cannot reach and affect his happiness. Therefore, since there is no motive to the contrary, it should be presumed that God's dealings with people would be impartial, and that there would be an advantage in serving him - not because people could place him under obligation, but because it was right and proper that such an advantage should come to them.

To impress this view on the mind, Elihu directs Job and his friends to look to the heavens - so lofty, grand, and sublime; to reflect on how much higher they are than man; and to remember that the great Creator is above all those heavens.

And thus they are to see that he is so far exalted that he is not dependent on man; that he cannot be affected by the righteousness or wickedness of his creatures; that his happiness is not dependent on them, and consequently that it is to be presumed that he would act impartially and treat all people as they deserved. There would be, therefore, an advantage in serving God.

And behold the clouds - Also far above us, and seeming to float in the heavens. The sentiment here is, that one view of the astonishing display of wisdom and power above us must extinguish every feeling that he will be influenced in his dealings as people are in theirs, or that he can gain or suffer anything by the good or bad behavior of his creatures.
