What does Genesis 27:39 mean?
Esau, crying in despair, has asked Isaac to bless him in any way possible, in spite of the fact that nearly all of the blessing has been given to Jacob (Genesis 27:27–29). Now Isaac responds, but it doesn't sound like a blessing.Isaac had blessed Jacob with the dew of heaven and the fatness of the earth, perhaps referring to the successful growing of well-watered crops and successful herds of animals. Now he confers on Esau what appears to be the exact opposite of this. He tells Esau that his dwelling will be away from the fatness of the earth and the dew of heaven. Perhaps this describes the nomadic life of a wandering tribe.
Eventually, Esau's descendants will become the nation known as Edom. These Edomites will live in the mountainous land of Seir, and bitterly conflict with the nation of Israel, which will descend from Jacob. The book of Obadiah predicts the eventual ruin of the Edomite people.
