Look! It is I who have created the blacksmith who fans coals in the fire, and produces a weapon for his purpose. It is I who have created the ravager to wreak havoc;

so will my message be that goes out of my mouth it won't return to me empty. Instead, it will accomplish what I desire, and achieve the purpose for which I sent it.
