Job 42:6

"And said, O my God, I am ashamed and blush to lift up my face to thee, my God: for our iniquities are increased over our head, and our trespass is grown up unto the heavens."

"He hath cast me into the mire, and I am become like dust and ashes."

"And I set my face unto the Lord God, to seek by prayer and supplications, with fasting, and sackcloth, and ashes:"

"Surely after that I was turned, I repented; and after that I was instructed, I smote upon my thigh: I was ashamed, yea, even confounded, because I did bear the reproach of my youth."

"And he took him a potsherd to scrape himself withal; and he sat down among the ashes."
