'Mourning' in the Bible

I will oppress Ariel,and there will be mourning and crying,and she will be to Me like an Ariel.

Beat your breasts in mourningfor the delightful fields and the fruitful vines,

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.
