In a trial for murder the accused was not to be condemned on the testimony of one witness, even though circumstantial evidence might be strong against him. The Lord's direction was, "Whoso killeth any person, the murderer shall be put to death by the mouth of witnesses: but one witness shall not testify against any person to cause him to die." Numbers 35:30. It was Christ who gave to Moses these directions for Israel; and when personally with His disciples on earth, as He taught them how to treat the erring, the Great Teacher repeated the lesson that one man's testimony is not to acquit or condemn. One man's views and opinions are not to settle disputed questions. In all these matters two or more are to be associated, and together they are to bear the responsibility, "that in the mouth of two or three witnesses every word may be established." Matthew 18:16.

I mordsager måtte den anklagede ikke dømmes på et enkelt vidnes udsagn, selv om omstændighederne tydede på, at han var skyldig. Herren sagde: "Når nogen slår et menneske ihjel, må man kun dræbe manddraberen efter flere vidners udsagn. Et enkelt vidnes udsagn er ikke nok til en dødsdom." 4. Mos. 35, 30.
