Esau said, “Isn’t that why he’s named Jacob? He’s cheated me twice already: He took my rights as firstborn, and now he’s taken my blessing.” So he asked, “Haven’t you saved a blessing for me?”
You know that afterwards, when he wanted to receive the blessing that the firstborn son was to receive, he was rejected. Even though he begged and cried for the blessing, he couldn’t do anything to change what had happened.
