Deuteronomy 17:6-12

17:6 At the testimony of two or three witnesses they must be executed. They cannot be put to death on the testimony of only one witness. 17:7 The witnesses must be first to begin the execution, and then all the people are to join in afterward. In this way you will purge evil from among you.

17:8 If a matter is too difficult for you to judge – bloodshed, legal claim, or assault – matters of controversy in your villages – you must leave there and go up to the place the Lord your God chooses. 17:9 You will go to the Levitical priests and the judge in office in those days and seek a solution; they will render a verdict. 17:10 You must then do as they have determined at that place the Lord chooses. Be careful to do just as you are taught. 17:11 You must do what you are instructed, and the verdict they pronounce to you, without fail. Do not deviate right or left from what they tell you. 17:12 The person who pays no attention to the priest currently serving the Lord your God there, or to the verdict – that person must die, so that you may purge evil from Israel.
