Job 35:3

“For thou saidst, what advantage will it be unto thee? etc.] Meaning that his righteousness, his holy life and conversation, were of no avail to him: he received no more benefit by being righteous than if he was wicked, since God destroyed one as well as another; and since his righteousness did not secure him from afflictions and calamities, it was of no advantage to him; he had not said so in so many words, but it is inferred from what he had said, (<180922>Job 9:22 10:15). Man’s own righteousness is of no advantage to him as to justification before God, and acceptance with him, nor in the business of salvation, or with respect to heaven and happiness, so as to give a right and title to it;…”

“Rather, explanatory of "this" in Job 35:2, "That thou sayest (to thyself, as if a distinct person) What advantage is it (thy integrity) to thee? What profit have I (by integrity) more than (I should have) by my sin?" that is, more than if I had sinned (Job 34:9). Job had said that the wicked, who use these very words, do not suffer for it (Job 21:13-15); whereby he virtually sanctioned their sentiments. The same change of persons from oblique to direct address occurs (Job 19:28; Job 22:17).”

“For thou saidst - Another sentiment of a similar kind which Elihu proposes to examine. He had already adverted to this sentiment of Job in Job 34:9, and examined it at some length, and had shown in reply to it that God could not be unjust, and that there was great impropriety when man presumed to arraign the justice of the Most High. He now adverts to it again in order to show that God could not be benefited or injured by the conduct of man, and that he was, therefore, under no inducement to treat him otherwise than impartially. What advantage will it be unto thee? - see the notes at Job 34:9. The phrase “unto thee,” refers to Job himself. He had said this to himself; or to his own soul.…”

“Thou saidst - Another imputation upon God. Unto thee - Unto me; such changes of persons being frequent in the Hebrew language. What profit, &c. - God does not reward so much as I deserve. But it was not fair to charge this upon Job, which he had neither directly nor indirectly affirmed. Job 35:5”

“what advantage: Job 9:21, Job 9:22, Job 10:15, Job 21:15, Job 31:2, Job 34:9; Psa 73:13; Mal 3:14 If I be cleansed from my sin: or, by it more than by my sin Job 35:4”
