Genesis 27:39-41

39Then Isaac his father answered and said to him: “Behold, your dwelling shall be of the fatness of the earth, And of the dew of heaven from above.

40By your sword you shall live, And you shall serve your brother; And it shall come to pass, when you become restless, That you shall break his yoke from your neck.”

41So Esau hated Jacob because of the blessing with which his father blessed him, and Esau said in his heart, “The days of mourning for my father are at hand; then I will kill my brother Jacob.”
