Ezekiel 46:19-20

Then he brought me through the entrance, which was at the side of the gate, to the north row of the holy chambers for the priests, and behold, a place was there at the extreme western end of them. And he said to me, “This is the place where the priests shall boil the guilt offering and the sin offering, and where they shall bake the grain offering, in order not to bring them out into the outer court and so transmit holiness to the people.”
