Verse 10

And Esau said, Is he not rightly called Jacob? for he has supplanted me twice, he took away my birthright and now he has taken away my blessing; and Esau wept greatly; and when Isaac heard the voice of his son Esau weeping, Isaac said unto Esau, What can I do, my son, thy brother came with subtlety and took away thy blessing; and Esau hated his brother Jacob on account of the blessing that his father had given him, and his anger was greatly roused against him.
