Ezekiel 46:22-26

In the four corners of the courtyard there were enclosed courtyards, forty cubits long and thirty wide; these four in the corners were the same size.

And there was a row of masonry all around in them, around the four of them, and cooking hearths were made under the rows all around.

Then he said to me, “These are the cooking places where the ministers of the house shall cook the sacrifices of the people.”
