Deuteronomy 17:9

And Moses said to his father-in-law, “Because the people come to me to inquire of God.

“If the thief is not caught, then the owner of the house shall appear before the judges to determine whether he laid his hands on his neighbor’s property.

then both the men who have the dispute shall stand before Yahweh, before the priests and the judges who will be in office in those days.

“Then the priests, the sons of Levi, shall come near, for Yahweh your God has chosen them to minister for Him and to bless in the name of Yahweh; and every dispute and every assault shall be settled by them.

“If there is a dispute between men and they go to court for judgment, and the judges judge their case, and they justify the righteous and condemn the wicked,

“And in a dispute, they shall take their stand to judge; they shall judge it according to My judgments. They shall also keep My laws and My statutes in all My appointed times and keep My sabbaths holy.

“Thus says Yahweh of hosts, ‘Ask now the priests about the law:

“Thus says Yahweh of hosts, ‘If you will walk in My ways and if you will keep the responsibility given by Me, then you will also render justice in My house and also keep My courts, and I will grant you access to walk among these who are standing here.

“For the lips of a priest should keep knowledge, and men should seek instruction from his mouth; for he is the messenger of Yahweh of hosts.
