15 But 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 come near to me to minister unto me, and they shall stand before me to offer unto me the fat and the blood, saith Yahweh Elohim:

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

23 And they shall teach my people the difference between the holy and profane, and cause them to discern between the unclean and the clean.

24 And in controversy they shall stand in judgment; and they shall judge it according to my judgments: and they shall keep my Torah and my statutes in all mine assemblies; and they shall hallow my Sabbaths.
