Deuteronomy 17:9
8 If a matter is too difficult for you to judge—bloodshed, legal claim, or assault—matters of controversy in your villages—you must leave there and go up to the place the Lord your God chooses. 9 You will go to the Levitical priests and the judge in office in those days and seek a solution; they will render a verdict. 10 You must then do as they have determined at that place the Lord chooses. Be careful to do just as you are taught.
Malachi 2:4
3 I am about to discipline your children and will spread offal on your faces, the very offal produced at your festivals, and you will be carried away along with it. 4 Then you will know that I sent this commandment to you so that my covenant may continue to be with Levi,” says the Lord of Heaven’s Armies. 5 “My covenant with him was designed to bring life and peace. I gave its statutes to him to fill him with awe, and he indeed revered me and stood in awe before me.
Notes and References
"... The interpretive tradition embraced by the texts we will investigate, and texts related to them, is a written tradition with particular priestly concerns. These concerns embrace the temple and all that pertains to it, including the proper ritual calendar and the correct performance of the cult and the festival rituals. In addition, the tradition has a strong interest in matters of purity and impurity, in which the laws of levitical and priestly purity are extended to cover the entire people of Israel. This priestly-levitical line of interpretation, which appears in works that were composed at least as early as the third century B.C.E., relies on a set of scriptural passages concerning the role of Levi and his heirs the priests in interpretation, teaching, and instruction: Deuteronomy 17:8-13; 33:10; and Malachi 2:4-7. These scriptural passages form the basis for a priestly scribal tradition of written interpretation of Scripture held in the hands of the priests ..."
