Ezekiel 46:20-21

20And he said unto me, This is the place where the priests shall boil the trespass-offering, and the sin-offering, [and] where they shall bake the oblation, that they bring them not out into the outer court, so as to hallow the people.

21And 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.
