Deuteronomy 17:2-13

2If a man or woman living among you in one of the towns the Lord gives you is found doing evil in the eyes of the Lord your God in violation of his covenant, 3and contrary to my command has worshiped other gods, bowing down to them or to the sun or the moon or the stars in the sky, 4and this has been brought to your attention, then you must investigate it thoroughly. If it is true and it has been proved that this detestable thing has been done in Israel, 5take the man or woman who has done this evil deed to your city gate and stone that person to death. 6On the testimony of two or three witnesses a person is to be put to death, but no one is to be put to death on the testimony of only one witness. 7The hands of the witnesses must be the first in putting that person to death, and then the hands of all the people. You must purge the evil from among you. 8If cases come before your courts that are too difficult for you to judge—whether bloodshed, lawsuits or assaults—take them to the place the Lord your God will choose. 9Go to the Levitical priests and to the judge who is in office at that time. Inquire of them and they will give you the verdict. 10You must act according to the decisions they give you at the place the Lord will choose. Be careful to do everything they instruct you to do. 11Act according to whatever they teach you and the decisions they give you. Do not turn aside from what they tell you, to the right or to the left. 12Anyone who shows contempt for the judge or for the priest who stands ministering there to the Lord your God is to be put to death. You must purge the evil from Israel. 13All the people will hear and be afraid, and will not be contemptuous again.
