Ezekiel 46:23

On the inside, around each of the four courts was a row of masonry, with hearths made at the bottom of the rows all around .

Around the inside of each of the four courts was a ledge of stone, with places for fire built all around under the ledge.

And there was a row of building round about in them, round about them four, and it was made with boiling places under the rows round about.
