Ezekiel 46:19-20

19Then he [my guide] brought me through the entrance, which was at the side of the gate, into the holy chambers for the priests, which faced the north; and behold, a place was there at their extreme westward end.

20He said to me, “This is the place where the priests shall boil (cook) the guilt offering and the sin offering, and where they shall bake the grain offering, so that they do not bring them out into the outer courtyard to transmit holiness to the people.”
