Isaiah 54:16-17

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 wreak havoc; 17no 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 .
