Deuteronomy 17:1-10

“You shall not sacrifice to the LORD your God an ox or sheep with a blemish or any defect, for that is a detestable thing to the LORD your God. “If there is discovered among you, within any of your cities, which the LORD your God is giving you, a man or a woman who does evil in the sight of the LORD your God, by transgressing (violating) His covenant, and has gone and served other gods and worshiped them, or the sun or the moon or any of the heavenly host, [doing these things] which I have commanded not to do, and if it is told to you and you hear about it, then you shall investigate thoroughly [all the charges]. If it is confirmed beyond doubt that this detestable thing has been done in Israel, then you shall bring that man or that woman who has done this evil thing to the gates [of your city] and you shall stone the man or the woman to death. On the evidence of two or three witnesses, he who is to die shall be put to death; he shall not be put to death on the evidence of [only] one witness. The hand of the witnesses shall be the first against him to put him to death, and afterward the hand of all the people. So you shall remove the evil from among you. “If any case is too difficult for you to judge—between one kind of homicide and another, between one kind of lawsuit and another, between one kind of assault and another, being controversial issues in your courts—then you shall arise and go to the place which the LORD your God chooses. So you shall come to the Levitical priests or to the judge who is in office at that time, and you shall consult them and they will declare to you the verdict in the case. You shall act in accordance with the terms of the verdict which they declare to you from that place which the LORD chooses. You shall be careful to act in accordance with all of their instructions.
