Job 2:8

And he took him a potsherd to scrape himself withal, evidently to relieve the intolerable itching of the festering sores; and he sat down among the ashes, to indicate that he was submerged in grief and mourning. The few words paint a picture of such utter degradation and misery after the great happiness which Job had enjoyed, that the contrast is extremely shocking. It is but seldom that a believer is so severely tried as was Job, and therefore his example serves to encourage and inspire the children of God for all times.
