Ezekiel 42:10; Ezekiel 42:13

10 In the thickness of the wall of the court toward the east, facing the separate area and facing the building, there were chambers.

13 Then he said to me, "The north chambers and the south chambers, which are opposite the separate area, they are the holy chambers where the priests who are near to the LORD shall eat the most holy things. There they shall lay the most holy things, the grain offering, the sin offering and the guilt offering; for the place is holy.
