A Life Cycle

When Isaac has only one blessing to give and yet has two sons, he can't alter his thinking.When Esau cried out for a blessing Isaac says he has handed out one—as if his hands are tied, his mind a blank, as if he's been tendered only a few words of blessing.Is  he repeating his own life story with his two sons as the actors? Is that the way some play out  life? Is their life a cycle of repetitions?
