What does Genesis 27:30 mean?
Jacob, with the help and insistence of his mother Rebekah, has pulled off an unlikely deception. It's true that Jacob's father was old and blind, but to trick him into giving what was apparently an irrevocable family blessing was quite an accomplishment (Genesis 27:6–17).One thing that almost kept Isaac from believing that Jacob was Esau was that he was there too quickly. It seemed unlikely that Esau could have killed and prepared his game so soon after being sent out by his father. Jacob's answer was that God's blessing made it possible. In truth, Jacob arrived early because he had to deliver his meal to Isaac and receive the blessing before Esau returned, just as his father had requested (Genesis 27:1–5).
Now we see just how close the whole plan was to blowing up. Jacob had scarcely left Isaac's presence, blessing in hand, when Esau entered with his own meal for Isaac. Now the scam will be revealed, too late, but with consequences all the same.
