Deuteronomy 19:15-21 - Laws Concerning Witnesses

¹⁵ One witness shall not rise against a man in any manner trespass or sin, whatsoever sin a man sinneth: But at the mouth of two witnesses or of three witnesses shall all matters be tried.

¹⁶ If an unrighteous witness rise up against a man to accuse him of trespass: ¹⁷ then let both the men which strive together stand before the LORD, before the priests and the judges which shall be in those days, ¹⁸ and let the judges enquire a good. And if the witness be found false and that he hath given false witness against his brother, ¹⁹ then shall ye do unto him as he had thought to do unto his brother, and so thou shalt put evil away from thee. ²⁰ And other shall hear and fear and shall henceforth commit no more any such wickedness among you. ²¹ And let thine eye have no compassion, but life for life, eye for eye, tooth for tooth, hand for hand, and foot for foot.
