Genesis 27:37-40

37Isaac answered Esau, “I have made him your master, and I have made all his brothers serve him. I’ve provided fresh grain and new wine for him. What is left for me to do for you, Son?”

38Esau asked, “Do you have only one blessing, Father? Bless me too, Father!” And Esau sobbed loudly.

39His father Isaac answered him, “The place where you live will lack the fertile fields of the earth and the dew from the sky above.

40You will use your sword to live, and you will serve your brother. But eventually you will gain your freedom and break his yoke  off your neck.”
