Deuteronomy 19:15-21 - Laws Concerning Witnesses

¹⁵ “One witness cannot establish any wrongdoing or sin against a person, whatever that person has done. A fact must be established by the testimony of two or three witnesses.

¹⁶ “If a malicious witness testifies against someone accusing him of a crime, ¹⁷ the two people in the dispute must stand in the presence of the Lord before the priests and judges in authority at that time. ¹⁸ The judges are to make a careful investigation, and if the witness turns out to be a liar who has falsely accused his brother, ¹⁹ you must do to him as he intended to do to his brother. You must purge the evil from you. ²⁰ Then everyone else will hear and be afraid, and they will never again do anything evil like this among you. ²¹ You must not show pity: life for life, eye for eye, tooth for tooth, hand for hand, and foot for foot.
