Deuteronomy 19:18-20

World English Bible

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 you shall do to him as he had thought to do to his brother. So you shall remove the evil from among you. ²⁰ Those who remain shall hear, and fear, and will never again commit any such evil among you.
