Genesis 27:40 ASV

³⁸  And Esau said unto his father, Hast thou but one blessing, my father? Bless me, even me also, O my father. And Esau lifted up his voice, and wept.

³⁹  And Isaac his father answered and said unto him, Behold, of the fatness of the earth shall be thy dwelling, And of the dew of heaven from above.

⁴⁰  And by thy sword shalt thou live, and thou shalt serve thy brother. And it shall come to pass, when thou shalt break loose, That thou shalt shake his yoke from off thy neck.

⁴¹  And Esau hated Jacob because of the blessing wherewith his father blessed him. And Esau said in his heart, The days of mourning for my father are at hand. Then will I slay my brother Jacob.

⁴²  And the words of Esau her elder son were told to Rebekah. And she sent and called Jacob her younger son, and said unto him, Behold, thy brother Esau, as touching thee, doth comfort himself, `purposing' to kill thee.
