Deuteronomy 17:2-5

2In one of the cities the Lord your God is giving you, there may be a man or woman among you who is doing what the Lord considers evil. This person may be disregarding the conditions of the Lord’s promise

3by worshiping and bowing down to other gods, the sun, the moon, or the whole army of heaven. I have forbidden this.

4When you are told about it, investigate it thoroughly. If it’s true and it can be proven that this disgusting thing has been done in Israel,

5then bring the man or woman who did this evil thing to the gates of your city, and stone that person to death.
