selling his birthright was looked on as lack of faith in the new testament. it showed he put more value on getting something for himself for the moment than holding onto something of value from his father.The birthright was a legacy handed down from his father and should have meant more to him than a bowl of soup.It shows that Esau's values and morals were more earthly. Jacob proved he was deceitful and couldn't be trusted and would easily betray anyone to get what he wanted. I think the saddest part is that he deceived his father, if you can lie that easily to your father then you have no character, no morals,no values at all
