Isaiah 57:11

And of whom hast thou been afraid or feared that thou hast lied and hast not remembered Me, nor laid it to thy heart? In spite of her faithlessness she is utterly callous and indifferent; she is apparently lost to every good influence. Have not I held My peace even of old, being patient in spite of her apostasy, holding back wrath and punishment, and thou fearest Me not? Jehovah had not treated Israel so as to cause any one in the nation to live in terror of Him; the apostates had no excuse for their action. The entire section pictures the tireless seeking of the renegade people after the vanity of idolatry and of heathen customs surely a sad waste of energy! Therefore Jehovah now, in a burst of holy irony, calls them to task.
