16 "See, it is I who created the blacksmith
       who fans the coals into flame
       and forges a weapon fit for its work.
       And it is I who have created the destroyer to work havoc;

 17 no weapon forged against you will prevail,
       and you will refute every tongue that accuses you.
       This is the heritage of the servants of the LORD,
       and this is their vindication from me,"
       declares the LORD.
