'Hearth' in the Bible

Everything that part of their carcass falls on becomes unclean; an oven, or a small stove shall be smashed; they are unclean, and shall be unclean to you.

For my days have vanished in smoke,And my bones have been scorched like a hearth.

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.”

The altar hearth shall be four cubits high, and from the altar hearth shall extend upwards four horns [one from each corner, each one cubit high].

Now the altar hearth shall be twelve cubits long by twelve wide, square in its four sides.
