Deuteronomy 17:9-13

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.

Then all the people will hear and be afraid, and will not act insolently again.
