Bible Verses About Murder: To be proved by two witnesses at least

The murderer shall be punished by witnesses: none shall be condemned upon the evidence of one man.

One witness shall not rise up against any man, whatsoever the sin or wickedness be: but in the mouth of two or three witnesses every word shall stand.
