Deuteronomy 19:10-21

19:10 You must not shed innocent blood in your land that the Lord your God is giving you as an inheritance, for that would make you guilty. 19:11 However, suppose a person hates someone else and stalks him, attacks him, kills him, and then flees to one of these cities. 19:12 The elders of his own city must send for him and remove him from there to deliver him over to the blood avenger to die. 19:13 You must not pity him, but purge out the blood of the innocent from Israel, so that it may go well with you.

Laws Concerning Witnesses

19:14 You must not encroach on your neighbor’s property, which will have been defined in the inheritance you will obtain in the land the Lord your God is giving you.

19:15 A single witness may not testify against another person for any trespass or sin that he commits. A matter may be legally established only on the testimony of two or three witnesses. 19:16 If a false witness testifies against another person and accuses him of a crime, 19:17 then both parties to the controversy must stand before the Lord, that is, before the priests and judges who will be in office in those days. 19:18 The judges will thoroughly investigate the matter, and if the witness should prove to be false and to have given false testimony against the accused, 19:19 you must do to him what he had intended to do to the accused. In this way you will purge evil from among you. 19:20 The rest of the people will hear and become afraid to keep doing such evil among you. 19:21 You must not show pity; the principle will be a life for a life, an eye for an eye, a tooth for a tooth, a hand for a hand, and a foot for a foot.
