Deuteronomy 17:6-8

Evangelical Heritage Version

⁶ A person is to be put to death on the basis of the testimony of two or three witnesses. No one is to be put to death based on the testimony of one witness. ⁷ The hands of the witnesses are to be the first ones raised against him when putting him to death, and after that the hands of all the other people. In that way you are to purge the evil from among you.

⁸ If a case is too difficult for you to make a decision, whether it involves a homicide, a lawsuit, or an assault, or any matters of controversy within the gates of your cities, then proceed by going up to the place that the Lord your God will choose.
