Deuteronomy 19:18-20

Revised Standard Version

¹⁸ the judges shall inquire diligently, and if the witness is a false witness and has accused his brother falsely, ¹⁹ then you shall do to him as he had meant to do to his brother; so you shall purge the evil from the midst of you. ²⁰ And the rest shall hear, and fear, and shall never again commit any such evil among you.
