Deuteronomy 17:2-7

2The Lord your God will give you towns to live in. You may hear that a man or a woman who lives in one of your towns has done a bad thing. He has done a sin that is against the covenant of the Lord your God.

3He may have started to worship false gods that I have commanded you not to worship. Perhaps he worships the sun, the moon or the stars.

4If you hear news like that, you must check the report carefully. If it is true that a wicked thing like that has happened in Israel,

5you must punish that person. Take the man or woman who has done that wicked thing to the gate of the town. Then you must throw stones at that person to kill them.

6But two or three people must agree about what the person has done. You must never kill anyone because of the words of only one person.

7The people who saw the wicked act must throw the first stones to kill the person. Then everyone else must also throw stones. In that way, you must remove evil acts from among you.
