Ezekiel 46:21-24

He then brought me to the outer court and led me around to its four corners, and I saw in each corner another court. In 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. Around the inside of each of the four courts was a ledge of stone, with places for fire built all around under the ledge. He said to me, “These are the kitchens where those who minister at the temple are to cook the sacrifices of the people.”
