Ezekiel 46:21-23

21He then brought me to the outer court and led me around to its four corners, and I saw in each corner another court.

22In the four corners of the outer court were enclosed courts, forty cubits long and thirty cubits wide; each of the courts in the four corners was the same size.

23Around the inside of each of the four courts was a ledge of stone, with places for fire built all around under the ledge.
