יָשֹׁ֣מּוּ יְשָׁרִ֣ים עַל־זֹ֑את וְ֝נָקִ֗י עַל־חָנֵ֥ף יִתְעֹרָֽר׃
Malbim on Job
The honest person, one who takes things at their face value, will take Job to be a righteous person and put the blame for his suffering on Providence. The innocent will presume Job was a hypocrite and only appeared to be upright, and was being punished for this.
Rashi on Job
and an innocent one If there is a righteous [man] who hears the mockery of these hypocrites.
