Ezekiel 46:21-24

21Then he brought me out to the outer court and led me around to the four corners of the court. And behold, in each corner of the court there was another court—

22in the four corners of the court were small courts, forty cubits long and thirty broad; the four were of the same size.

23On the inside, around each of the four courts was a row of masonry, with hearths made at the bottom of the rows all around.

24Then he said to me, "These are the kitchens where those who minister at the temple shall boil the sacrifices of the people."
