Deuteronomy 17:5

2 If there is any man or woman among you, in any of the towns which the Lord your God gives you, who does evil in the eyes of the Lord your God, sinning against his agreement,

3 By becoming a servant of other gods and worshipping them or the sun or the moon or all the stars of heaven, against my orders;

4 If word of this comes to your ears, then let this thing be looked into with care, and if there is no doubt that it is true, and such evil has been done in Israel;

5 Then you are to take the man or woman who has done the evil to the public place of your town, and they are to be stoned with stones till they are dead.

6 On the word of two or three witnesses, a man may be given the punishment of death; but he is not to be put to death on the word of one witness.

7 The hands of the witnesses will be the first to put him to death, and after them the hands of all the people. So you are to put away the evil from among you.

8 If you are not able to give a decision as to who is responsible for a death, or who is right in a cause, or who gave the first blow in a fight, and there is a division of opinion about it in your town: then go to the place marked out by the Lord your God;
