How do we know Job was unjustly accused?

Throughout the Book of Job, especially in dialogues like Job 16 and 18, Job maintains that he has a clear conscience and a witness in heaven. He appeals to God for an advocate to plead his case, which showcases his understanding of personal integrity. The narrative provides insight into Job's character, where he is portrayed not as wicked but as enduring suffering while holding fast to his faith in God. His reflections demonstrate that, despite the accusations against him, Job firmly believed in his complete trust in God for justification and acknowledgment of his faithfulness.
