TSK · Deuteronomy 21:5

Aaron lifted up his hands toward the people, and blessed them; and he came down from offering the sin offering, and the burnt offering, and the peace offerings.

At that time Yahweh set apart the tribe of Levi, to bear the ark of the covenant of Yahweh, to stand before Yahweh to minister to him, and to bless in his name, to this day.

and you shall come to the priests the Levites, and to the judge who shall be in those days: and you shall inquire; and they shall show you the sentence of judgment.

then both the men, between whom the controversy is, shall stand before Yahweh, before the priests and the judges who shall be in those days;

Whenever any controversy shall come to you from your brothers who dwell in their cities, between blood and blood, between law and commandment, statutes and ordinances, you shall warn them, that they not be guilty towards Yahweh, and so wrath come on you and on your brothers. Do this, and you shall not be guilty.
