Ezekiel 46:21-24

21Then he brought me forth into the outer court, and caused me to pass by the four corners of the court; and, behold, in every corner of the court there was a court.1 22In the four corners of the court there were courts joined of forty cubits long and thirty broad: these four corners were of one measure.23 23And there was a row of building all around in them, around the four of them, and it was made with boiling places under the rows on every side. 24Then said he to me, These are the places of them that boil, where the ministers of the house shall boil the sacrifice of the people.
