Deuteronomy 17:2-5

2Suppose a man or woman is discovered among you – in one of your villages that the Lord your God is giving you – who sins before the Lord your God and breaks his covenant

3by serving other gods and worshiping them – the sun, moon, or any other heavenly bodies which I have not permitted you to worship.

4When it is reported to you and you hear about it, you must investigate carefully. If it is indeed true that such a disgraceful thing is being done in Israel,

5you must bring to your city gates that man or woman who has done this wicked thing – that very man or woman – and you must stone that person to death.
