Job 36:21

“Take heed, regard not iniquity, etc.] Not any iniquity, as to show any approbation of it, love for it, and desire after it. All appearance of sin, of every sin, is to be abstained from; but particularly by the iniquity here meant may be the sin of impatience under his affliction; murmuring at the dealings of God with him; arraigning his justice, and saying very indecent things of him, as in (<183405>Job 34:5 35:2). Or it may mean the evil he had been guilty of in so earnestly desiring the night of death: for this thou hast chosen rather than affliction; chose rather to die than to be afflicted as he was; or chose rather to complain of God, as if he dealt hardly with him, and did not do…”

“regard--literally, "turn thyself to." iniquity--namely, presumptuous speaking against God (Job 34:5, and above, see on Job 36:17-18). rather than--to bear "affliction" with pious patience. Men think it an alleviation to complain against God, but this is adding sin to sorrow; it is sin, not sorrow, which can really hurt us (contrast Heb 11:25).”

“Take heed, regard not iniquity - That is, be cautious that in the view which you take of the divine government, and the sentiments which you express, you do not become the advocate of iniquity. Elihu apprehended this from the remarks in which he had indulged, and regarded him as having become the advocate of the same sentiments which the wicked held, and as in fact manifesting the same spirit. It is well to put a man who is afflicted on his guard against this, when he attempts to reason about the divine administration. For this hast thou chosen rather than affliction - That is, you have chosen rather to give vent to the language of complaint, than to bear your trials with resignation. “You…”

“Chosen - Thou hast chosen rather to quarrel with God, and censure his judgments, than quietly to submit to them. Job 36:22”
