Jessica run away with Lorenzo and  stolen from her father.  Freed from her father’s restraint, Jessica and Lorenzo spend their stolen wealth with carelessness, Jessica even trading the “turquoise,” which symbolize the engagement of her father and mother, for a monkey. Jessica’s heartless to her father contributes to Shylock’s increasingly dehumanization but also highlights the contrast between her behavior and Portia’s. While Jessica has recklessly spent their stolen money, Portia has carefully conserved her wealth to make her husband a debtor in their relationship. If it were not Portia’s assistance at the end of the play, the marriage between Jessica and Lorenzo probably would have ended in calamity.
