'Ashes' in the Bible

The peoples will be burned to ashes,like thorns cut down and burned in a fire.

He feeds on ashes.His deceived mind has led him astray,and he cannot deliver himself,or say, “Isn’t there a lie in my right hand?”

Will the fast I choose be like this:A day for a person to deny himself,to bow his head like a reed,and to spread out sackcloth and ashes?Will you call this a fastand a day acceptable to the Lord?

to provide for those who mourn in Zion;to give them a crown of beauty instead of ashes,festive oil instead of mourning,and splendid clothes instead of despair.And they will be called righteous trees,planted by the Lordto glorify Him.
