Deuteronomy 17:1-13

“Do not sacrifice to the Lord your God an ox or sheep with a defect or any serious flaw, for that is detestable to the Lord your God.  “If a man or woman among you in one of your towns that the Lord your God will give you is discovered doing evil in the sight of the Lord your God and violating his covenant  and has gone to serve other gods  by bowing in worship to the sun, moon, or all the stars in the sky   — which I have forbidden   —  and if you are told or hear about it, then investigate it thoroughly. If the report turns out to be true that this detestable act has been done in Israel, you are to bring out to your city gates that man or woman who has done this evil thing and stone them to death.  The one condemned to die is to be executed on the testimony of two or three witnesses.  No one is to be executed on the testimony of a single witness. The witnesses’ hands are to be the first in putting him to death, and after that, the hands of all the people.  You must purge the evil from you.  “If a case is too difficult for you — concerning bloodshed,  lawsuits,  or assaults   — cases disputed at your city gates,  then go up to the place the Lord your God chooses. You are to go to the Levitical priests and to the judge who presides at that time. Ask, and they will give you a verdict in the case. You must abide by the verdict they give you at the place the Lord chooses. Be careful to do exactly as they instruct you. You must abide by the instruction they give you and the verdict they announce to you. Do not turn to the right or the left from the decision they declare to you. The person who acts arrogantly, refusing to listen either to the priest who stands there serving the Lord your God or to the judge, must die. You must purge the evil from Israel. Then all the people will hear about it, be afraid, and no longer behave arrogantly.
