Deuteronomy 17:7

4 and you are told, and you have heard of it, then you shall inquire diligently. Behold, if it is true, and the thing certain, that such abomination is done in Israel,

5 then you shall bring out that man or that woman who has done this evil thing to your gates, even that same man or woman; and you shall stone them to death with stones.

6 At the mouth of two witnesses, or three witnesses, he who is to die shall be put to death. At the mouth of one witness he shall not be put to death.

7 The hands of the witnesses shall be first on him to put him to death, and afterward the hands of all the people. So you shall remove the evil from among you.

8 If there arises a matter too hard for you in judgment, between blood and blood, between plea and plea, and between stroke and stroke, being matters of controversy within your gates, then you shall arise, and go up to the place which the LORD your God chooses.

9 You shall come to the priests who are Levites and to the judge who shall be in those days. You shall inquire, and they shall give you the verdict.

10 You shall do according to the decisions of the verdict which they shall give you from that place which the LORD chooses. You shall observe to do according to all that they shall teach you.
