This adjective appears in Job 31:28, where Job declares that certain sins would be 'iniquity for judges'—crimes requiring judicial attention and punishment. In his oath of innocence, Job lists secret sins that might escape human notice, then names those that would be publicly prosecutable if discovered. Idolatry falls into this latter category: not just personal betrayal of God but a crime against the community requiring legal judgment. The phrase indicates offenses that fall under earthly courts' jurisdiction, violations so serious they demand judicial intervention.
