Deuteronomy 17:2-5

2“1If there is found in your midst, in any of your 2towns which the Lord your God is giving you, a man or a woman who does what is evil in the sight of the Lord your God, by violating His covenant,

3and that person has gone and 3served other gods and worshiped them, 4or the sun, the moon, or any of the heavenly 5lights, 6which I have commanded not to do,

4and if it is reported to you and you have heard about it, then you shall investigate thoroughly. And 7if it is true and the report is trustworthy that this detestable thing has been done in Israel,

5then you are to bring out to your gates that man or woman who has done this evil deed, that is, the man or the woman, and 8you shall stone them to 9death.
