Deuteronomy 19:17-19

Tree of Life Version

¹⁷ Then both people who have the dispute will stand before Adonai, before the kohanim and judges in charge at that time. ¹⁸ The judges are to investigate thoroughly, and if indeed the witness is a false witness and has testified falsely against his brother, ¹⁹ then you are to do to him just as he had plotted to do to his brother. So you will purge the evil from your midst.
