Albert Barnes Commentary Job 35:6

"If thou hast sinned, what effectest thou against him? And if thy transgressions be multiplied, what doest thou unto him?" — Job 35:6 (ASV)

If thou sinnest, what doest thou against him? - This should not be interpreted as designed to justify sin, or as saying that there is no evil in it, or that God does not regard it. That is not the point or scope of the remark of Elihu. His object is to show that God is not influenced in his treatment of his creatures as people are in their treatment of each other. He has no interest in being partial, or in treating them otherwise than they deserve. If they sin against him his happiness is not so marred that he is under any inducement to interpose by passion, or in any other way than that which is right.
