Deuteronomy 17:9-12

9Go to the Levitical priests and the judge who is serving at that time. Ask for their opinion, and they will give you their verdict

10at the place that the Lord will choose. Do what they tell you. Follow all their instructions carefully,

11and do what they tell you to do in their verdict. Do exactly what they tell you to do in their decision.

12If anyone deliberately disobeys the priest (who serves the Lord your God) or the judge, that person must die. You must get rid of this evil in Israel.
