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

“‘Whoever kills any person, the murderer shall be slain at the mouth of witnesses; but one witness shall not testify against any person that he die.

But if any man hates his neighbor, lies in wait for him, rises up against him, strikes him mortally so that he dies, and he flees into one of these cities;

One witness shall not rise up against a man for any iniquity, or for any sin, in any sin that he sins. At the mouth of two witnesses, or at the mouth of three witnesses, shall a matter be established.
