Whoever kills any person [intentionally], the murderer shall be put to death on the testimony of witnesses; but no one shall be put to death on the testimony of one witness.
But if he does not listen, take along with you one or two others, so that every word may be confirmed and upheld by the testimony of two or three witnesses.
THIS IS the third time that I am coming to you. By the testimony of two or three witnesses must any charge and every accusing statement be sustained and confirmed. [Deut. 19:15.]
One witness shall not prevail against a man for any crime or any wrong in connection with any sin he commits; only on the testimony of two or three witnesses shall a charge be established.
Any person who has violated and [thus] rejected and set at naught the Law of Moses is put to death without pity or mercy on the evidence of two or three witnesses. [Deut. 17:2-6.]
