As the narrative of Genesis continues, we learn that God's choice to inherit the promise of Abraham and become the Chosen People will rest with only one of Isaac and Rebekah's sons, Jacob instead of Esau. This isn't because Jacob is better than Esau, in fact, as this episode demonstrates, Jacob is a schemer willing to defraud even his own twin brother. What is it then? Grace, God's grace.
What then do we say about Jacob? There isn't any reason to like Jacob as Genesis presents him, we may think that Esau is a fool (that's Moses' narrative assessment), but a just because a family member is a fool doesn't mean we have the right to take advantage of him/her. Ultimately, Jacob will reap what he sows, but it will be a tragic story that didn't need to happen, he could have been a better man, he could have considered his brother above himself.
