Albert Barnes Commentary Job 34:32

"That which I see not teach thou me: If I have done iniquity, I will do it no more?" — Job 34:32 (ASV)

That which I see not, teach thou me - That is, in regard to my errors and sins. No prayer could be more appropriate than this. It is language suitable for every one who is afflicted, and who does not see clearly the reason why it is done. The sense is that, with a full belief that he is liable to error and sin, that he has a wicked and deceitful heart, and that God never afflicts without reason, he should go to him and ask him to show him “why” he has afflicted him.

He should not complain or fret; he should not accuse God of injustice or partiality; he should not attempt to cloak his offences, but should go and entreat him to reveal to him the sins of heart and life which have led to these calamities. Then only will he be in a state of mind in which he will be likely to be profited by trials.

If I have done iniquity, I will do no more - Admitting the possibility that he had erred. Who is there that cannot appropriately use this language when he is afflicted?
