'Hearth' in the Bible

“Command Aaron and his sons: This is the law of the burnt offering; the burnt offering itself must remain on the altar’s hearth all night until morning, while the fire of the altar is kept burning on it.

Its collapse will be like the shatteringof a potter’s jar, crushed to pieces,so that not even a fragment of potterywill be found among its shattered remains—no fragment large enough to take fire from a hearthor scoop water from a cistern.”

The altar hearth is seven feet high, and four horns project upward from the hearth.

The hearth is square, 21 feet long by 21 feet wide.
