Ezekiel 46:23

He said to me, “This is the place where the priests shall boil the trespass offering and the sin offering, and where they shall bake the meal offering, that they not bring them out into the outer court, to sanctify the people.”

Then he brought me out 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.

In the four corners of the court there were courts enclosed, forty cubits long and thirty wide. These four in the corners were the same size.

Then he said to me, “These are the boiling houses, where the ministers of the house shall boil the sacrifice of the people.”
