MSB⁽ⁱ⁾ ¹⁷ both parties to the dispute must stand in the presence of the LORD, before the priests and judges who are in office at that time. ¹⁸ The judges shall investigate thoroughly, and if the witness is proven to be a liar who has falsely accused his brother, ¹⁹ you must do to him as he intended to do to his brother. So you must purge the evil from among you. ²⁰ Then the rest of the people will hear and be afraid, and they will never again do anything so evil among you. ²¹ You must show no pity: life for life, eye for eye, tooth for tooth, hand for hand, and foot for foot.
