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

  28  And now, behold, I give unto you, and also unto my servant Joseph, the keys of this gift, which shall bring to light this ministry; and in the mouth of two or three ^bwitnesses shall every word be established.
