Ezekiel 42:1, 13

Then he (the angel) brought me out into the outer courtyard, toward the north; and he led me to the [attached] chamber which was opposite the separate area and opposite the building to the north.

Then he (the angel) said to me, “The north chambers and the south chambers, which are opposite the separate area, are the holy chambers where the priests who are close to the LORD shall eat the most holy offerings. There they shall place the most holy things—the grain offering, the sin offering, and the guilt offering—for the place is holy.
