'Hearth' in the Bible

Yet I will inflict Ariel, and there shall be mourning and lamentation, and it shall be to me like an altar hearth.

And he breaks it like a vessel of {a potter} breaks, [that] is crushed; he has no compassion, and no potsherd is found among its fragments {to take fire} from [the] hearth, or {to skim} water from [the] cistern."
