Adam Clarke's Bible Commentary Verse 3. What advantage will it be unto thee? ] As if he had said to God, "My righteousness cannot profit thee, nor do I find that it is of any benefit to myself." Or perhaps Elihu makes here a general assertion, which he afterwards endeavours to exemplify: Thou hast been reasoning how it may profit thee, and thou hast said, "What profit shall I have in righteousness more than in sin?"
Matthew Henry Commentary
Verses 1-8 - Elihu reproves Job for justifying himself more than God, and called his attention to the heavens. They are far above us, and God is far abov them; how much then is he out of the reach, either of our sins or of our services! We have no reason to complain if we have not what we expect, but should be thankful that we have better than we deserve.
