Genesis 27:39-41

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

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

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