Deuteronomy 17:6-12

61On the 2evidence of two witnesses or three witnesses, he who is to die shall be put to death; he shall not be put to death on the 3evidence of one witness. 74The hand of the witnesses shall be first against him to put him to death, and afterward the hand of all the people. 5So you shall purge the evil from your midst.

8“6If any case is too difficult for you to decide, between 7one kind of homicide or another, between 8one kind of lawsuit or another, and between 9one kind of assault or another, being cases of dispute in your 10courts, then you shall arise and go up to 11the place which the Lord your God chooses. 9So you shall come to 12the Levitical priest or the judge who is in office in those days, and you shall inquire of them and they will declare to you the verdict in the case. 10You shall do according to the 13terms of the verdict which they declare to you from that place which the Lord chooses; and you shall be careful to observe according to all that they teach you. 1114According to the 15terms of the law which they teach you, and according to the verdict which they tell you, you shall do; you shall not turn aside from the word which they declare to you, to the right or the left. 12The man who acts 16presumptuously by not listening to the priest who stands there to serve the Lord your God, nor to the judge, that man shall die; thus you shall purge the evil from Israel.
