Bible: Deuteronomy 19:15-21

19:15 A single witness may not testify 1  against another person for any trespass or sin that he commits. A matter may be legally established 2  only on the testimony of two or three witnesses. 19:16 If a false 3  witness testifies against another person and accuses him of a crime, 4  19:17 then both parties to the controversy must stand before the Lord, that is, before the priests and judges 5  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, 6  19:19 you must do to him what he had intended to do to the accused. In this way you will purge 7  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. 8
