Deuteronomy 19:17-19

American Standard Version

¹⁷ then both the men, between whom the controversy is, shall stand before Jehovah, before the priests and the judges that shall be in those days; ¹⁸ and the judges shall make diligent inquisition: and, behold, if the witness be a false witness, and have testified falsely against his brother; ¹⁹ then shall ye do unto him, as he had thought to do unto his brother: so shalt thou put away the evil from the midst of thee.
