TSK · Deuteronomy 21:5

Then Aaron lifted up his hands toward the people and blessed them and descended from making the sin offering, the burnt offering, and the peace offering.

At that time the LORD set apart the tribe of Levi to carry the ark of the LORD’s covenant, to stand before the LORD to serve him, and to formulate blessings in his name, as they do to this very day.

You will go to the Levitical priests and the judge in office in those days and seek a solution; they will render a verdict.

then both parties to the controversy must stand before the LORD, that is, before the priests and judges who will be in office in those days.

Whenever your countrymen who live in the cities bring a case before you(whether it involves a violent crime or other matters related to the law, commandments, rules, and regulations), warn them that they must not sin against the LORD. If you fail to do so, God will be angry with you and your colleagues, but if you obey, you will be free of guilt.
