Deuteronomy 17:8-9

“If any case arises requiring decision between one kind of homicide and another, one kind of legal right and another, or one kind of assault and another, any case within your towns that is too difficult for you, then you shall arise and go up to the place that the LORD your God will choose. And you shall come to the Levitical priests and to the judge who is in office in those days, and you shall consult them, and they shall declare to you the decision.
