Genesis 27:37-40

37But Isaac answered Esau, “Look, I have made him a master over you, have given him all of his relatives as his servants, and have sustained him with grain and new wine. What then can I do for you, my son?”

38Esau said to his father, “Do you have only one blessing, my father? Bless me too, my father!” And Esau wept loudly.

39His father Isaac answered him, Look, your dwelling place will be away from the richness of the land, away from the dew of the sky above.

40You will live by your sword, and you will serve your brother. But when you rebel, you will break his yoke from your neck.
