'Ashes' in the Bible

And the nations will be burned as if to ashes; like cut thorn bushes, they will be set ablaze.

He tends ashes. A deceived mind has lead him astray. It cannot be his life, nor can he say, "There's a lie in my right hand."

"Is this the kind of fast that I have chosen, merely a day for a person to humble himself? Is it merely for bowing down one's head like a bulrush, for lying on sackcloth and ashes? Is this what you call a fast, an acceptable day to the LORD?

to provide for those who grieve in Zion to bestow on them a crown of beauty instead of ashes, the oil of gladness instead of mourning, a mantle of praise instead of a spirit of despair." "Then people will call them "Oaks of Righteousness", "The Planting of the LORD", in order to display his splendor.
