Ezekiel 42:13

And he said to me, These chambers on the north and those on the south which are in front of the spaces, are the chambers of the sanctuary, in which the priests the sons of Sadduk, who come near to the Lord, are to eat the holy meats and where they are to lay up the most holy things, the sacrifice and the sin offerings and the trespass offerings. Because this is a holy place

And he said to me, The chambers toward the north, and the chambers toward the south, in front of the void spaces, these are the chambers of the sanctuary, wherein the priests the sons of Sadduc, who draw nigh to the Lord, shall eat the most holy things: and there shall they lay the most holy things, and the meat-offering, and the sin-offerings, and the trespass-offerings; because the place is holy.
