Ezekiel 42:1, 13

Then he brought me forth into the utter court, the way toward the north: and he brought me into the chamber that was over against the separate place, and which was before the building toward the north.

Then said he unto me, The north chambers and the south chambers, which are before the separate place, they be holy chambers, where the priests that approach unto the LORD shall eat the most holy things: there shall they lay the most holy things, and the meat offering, and the sin offering, and the trespass offering; for the place is holy.
