'Hearth' in the Bible

Then I will harass Ariel,And she will be a city of mourning and lamenting (crying out in grief)Yet she will be like an Ariel [an altar hearth] to Me.

“Whose collapse is like the smashing of a potter’s jar,Crushed so savagelythat there cannot be found among its pieces a potsherd [large enough]To take [coals of] fire from a fireplace,Or to scoop water from a cistern.”
