Deuteronomy 19:18 WEB

¹⁶  If an unrighteous witness rise up against any man to testify against him of wrong-doing,

¹⁷  then both the men, between whom the controversy is, shall stand before Yahweh, before the priests and the judges who shall be in those days;

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

¹⁹  then shall you do to him, as he had thought to do to his brother: so shall you put away the evil from the midst of you.

²⁰  Those who remain shall hear, and fear, and shall henceforth commit no more any such evil in the midst of you.
