Deuteronomy 17:8-9

8“1If any case is too difficult for you to decide, between 2one kind of homicide or another, between 3one kind of lawsuit or another, and between 4one kind of assault or another, being cases of dispute in your 5courts, then you shall arise and go up to 6the place which the Lord your God chooses.

9So you shall come to 7the Levitical priest or the judge who is in office in those days, and you shall inquire of them and they will declare to you the verdict in the case.
