Deuteronomy 19:16-20

16If a malicious witness arises to accuse a person of wrongdoing,

17then both parties to the dispute shall appear before the Lord, before the priests and the judges who are in office in those days.

18The judges shall inquire diligently, and if the witness is a false witness and has accused his brother falsely,

19then you shall do to him as he had meant to do to his brother. So you shall purge the evil from your midst.

20And the rest shall hear and fear, and shall never again commit any such evil among you.
