Deuteronomy 19:15-21 - Laws Concerning Witnesses
15 One witness I shall not rise up, against a man for any iniquity, or for any sin, with regard to any sin that he may commit, - at the mouth of two witnesses or at the mouth of three witnesses, must a matter be establish.
16 When there shall rise up a wrongful witness against a man, - to answer against him perversely, 17 then shall the two men who are at variance stand before Yahweh, - before the priests and the judges who shall be in those days; 18 and the judges shall make diligent inquisition, - and lo! if the witness be, a false witness and, falsely, have answered against his brother, 19 then shall ye do unto him as he had thought to de unto his brother, - so shalt thou consume the wicked thing out of thy midst; 20 and, they who remain shall hear and fear, - and not go on to do again according to this wicked thing, in thy midst: 21 neither shall thine eye pity, - life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
