Job 42:6

Repent. Job was presumably still sitting on the ash heap on which he had thrown himself when his disease first smote him (chapter 2:8). His friends had urged him to repent, but their appeal was based on the assumption that he had committed sins of which he was not guilty. His eventual repentance was for his mistaken attitude toward God. Compare Job’s repentance with that of Peter (Luke 5:8), and of Isaiah (Isaiah 6:5). In each case the manifestation of God achieved what no argument based on human tradition could accomplish.
