'Ashes' in the Bible

And they will make their voice heard [as they wail loudly] over youAnd they will cry bitterly.They will throw dust on their heads;They will wallow in ashes.

“You profaned your sanctuariesBy the great quantity of your sins and the enormity of your guilt,By the unrighteousness of your trade.Therefore I have brought forth a fire from your midst;It has consumed you,And I have reduced you to ashes on the earthIn the sight of all who look at you.
