Deuteronomy 17:8-12

“If a case is too difficult for you to decide, between one kind of homicide or another, between one kind of lawsuit or another, and between one kind of assault or another, that are cases of dispute in your courts, then you shall arise and go up to the place which the Lord your God chooses.

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

Then you shall act in accordance with the terms of the verdict which they declare to you from that place which the Lord chooses; and you shall be careful to act in accordance with everything that they instruct you to do.

In accordance with the terms of the law about which they instruct you, and in accordance with the verdict which they tell you, you shall act; you shall not turn aside from the word which they declare to you, to the right or the left.

But the person who acts insolently by not listening to the priest who stands there to serve the Lord your God, nor to the judge, that person shall die; so you shall eliminate the evil from Israel.
