Ezekiel 44:15-16

15But the priests, the Levites, the sons of Zadok, that kept the charge of my sanctuary when the children of Israel went astray from me, they shall approach unto me to minister unto me, and they shall stand before me to present unto me the fat and the blood, saith the Lord Jehovah.

16They shall enter into my sanctuary, and they shall approach unto my table, to minister unto me, and they shall keep my charge.
