Deuteronomy 19:17-20

17Then both the men, between whom the controversy is, shall stand before the Lord, before the priests and the judges, which shall be in those days;

18And the judges shall make diligent inquisition: and, behold, if the witness be a false witness, and hath testified falsely against his brother;

19Then shall ye do unto him, as he had thought to have done unto his brother: so shalt thou put the evil away from among you.

20And those which remain shall hear, and fear, and shall henceforth commit no more any such evil among you.
