Ezekiel 46:19-23

Then he brought me through the entrance, which was at the side of the gate, into the holy chambers for the priests, which faced north; and behold, a place was there at the extreme rear toward the west.

And he said to me, “This is the place where the priests shall boil the guilt offering and the sin offering, and where they shall bake the grain offering, so that they do not bring them out into the outer courtyard and transfer holiness to the people.”

Then he brought me out into the outer courtyard and led me across to the four corners of the courtyard; and behold, in every corner of the courtyard there was a small courtyard.

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.
