Deuteronomy 19
18 Ref and the judges shall make diligent inquisition: and, behold, if the witness be a false witness, and have testified falsely against his brother;
19 Ref 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.
20 Ref And those that remain shall hear, and fear, and shall henceforth commit no more any such evil in the midst of thee.
