And there's a slight sense that Isaiah knows this, because he says, this is God speaking, of course, "I have called thee by thy name though thou hast not known me." I think it's recognized that Cyrus doesn't realize that he's acting under orders from Jehovah.
Y da una ligera sensación de que Isaías lo sabe, porque dice, por supuesto, es Dios quien habla: "Te he llamado por tu nombre mas tú no me conoces". Pienso que ha reconocido que Ciro no se da cuenta de que está actuando bajo las órdenes de Jehová.
