Deuteronomy 17:5-7

Evangelical Heritage Version

⁵ then you are to bring that man or that woman who has committed this evil out to your city gate, and you are to stone that person to death, whether man or woman.

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.
