Final Blessing (Ch. 9:11-15). 

        These verses (or 9:8-15) are the prophet’s addition as he records his message for posterity. However pessimistic a prophet might be about his own generation, he was com­pletely optimistic about the future. Sooner or later God’s purpose in the choice of Israel was bound to be vindicated. A comparison with Joel 3:18f suggests that he is using traditional language. Isaiah consistently uses pictures of transformed nature as implying transformed men.
