Genesis 27:37-41
English Standard Version
Chapter 27
37Isaac answered and said to Esau, "Behold, I have made him lord over you, and all his brothers I have given to him for servants, and with grain and wine I have sustained him. What then can I do for you, my son?" 38Esau said to his father, "Have you but one blessing, my father? Bless me, even me also, O my father." And Esau lifted up his voice and wept.
40By your sword you shall live, and you shall serve your brother; but when you grow restless you shall break his yoke from your neck."
41Now Esau hated Jacob because of the blessing with which his father had blessed him, and Esau said to himself, "The days of mourning for my father are approaching; then I will kill my brother Jacob."
