Ezekiel 46:20-21

20And 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 grain offering, so that they do not bring them out into the outer court to sanctify the people.”

21Then he brought me out into the outer court and caused me to pass by the four corners of the court; and in fact, in every corner of the court there was another court.
