Ezekiel 46:21-23

21Then he brought me forth into the utter 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 round about in them, round about them four, and it was made with boiling places under the rows round about.
