What happened to Esau when he later tried to get the blessing?
When Esau later sought the blessing, he was rejected. Though he sought it carefully with tears, he found no place of repentance. He hoped his father Isaac would change his mind, but Isaac would not, because that was not the custom. Esau also bewailed having missed both birthright and blessing.
Les explains that Esau had earlier sold his birthright for one morsel of food, the bowl of bean soup, and it did not bother him. Then afterward, thirty-seven years later, when he would have inherited the blessing or the double portion, he was rejected. He found no place of repentance, though he sought it carefully with tears. Les suggests Esau's repentance was directed toward hoping his father would change his mind. Esau was so distraught that he thought his weeping and crying could get Isaac to change his mind, but Isaac would not, because that was not the custom. Esau was also bewailing that he had missed the birthright and the blessing. Les ties Esau's problem back to Cain: no faith. Esau saw no significance in spiritual things, just as Cain saw no significance in what God said.
