Ezekiel 46:22-24 American Standard Version (ASV)

22. In the four corners of the court there were courts inclosed, forty cubits long and thirty broad: these four in the corners were of one measure.

23. And there was a wall round about in them, round about the four, and boiling-places were made under the walls round about.

24. Then said he unto me, These are the boiling-houses, where the ministers of the house shall boil the sacrifice of the people.
