Maybe Isaac didn't reverse the blessing of Abraham because he didn't bestow the blessing of Abraham. He bestowed A blessing upon Jacob (of whom he was suspicious), but it was a blessing of fatness of earth, dew of heaven, corn, wine, servants and dominion--but it was not the Blessing of Abraham. Then he blessed Esau with A blessing--of fatness, dew, live by sword, serve brother--and it too, was not the Blessing of Abraham. It was not until Isaac sent Jacob to Pandaran that he said specifically said THE blessing, ..."And give thee the blessing of Abraham to thee, and to thy seed with thee...(Gen 28; 3 &4). The blessing that God gave to Abraham promised an everlasting covenant between Abraham & and his seed to be their God, and to possess the land (Canaan) forever. And much more (Gen 17). None of this was present in the two prior blessings. Isaac gave The Blessing of Abraham to the right son--maybe he wasn't as old, blind, feeble and ineffective as we thought!
