Paul, of the tribe of Benjamin and from Jacob according to the lineage, writes regarding Jacob and Esau before either were born having done good or evil, that the Heavenly Father loved Jacob and hated Esau. (Romans 9:11——) Paul was a well trained Hebrew scholar and quoted what was penned by Malachi the prophet. (Malachi 1:2——) Neither of these that followed up on Jacob and Esau seem inclined to hint the wrestling was done between Esau's guardian angel and Jacob.
Now obviously Jacob before the wrestling was thinking in terms of his own and kindreds physical safety, and probably with good reason when he would come into contact with Esau on his return to his country.
So Jacob which means contender, sent a ‘peace’ offering to his brother and then while alone. Hosea 12 gives the student more insight to what precedent was set in Jacob the contender to Israel which means “God commands, orders or rules” .....
I see/read nothing that suggests that the Man “Angel” that Jacob contended with and prevailed has anything to do with it being Esau's guardian angel. Maybe Jacob needed reassurance that the birthright Esau sold him for a ‘red’ bowl of pottage, and the blessing he was given was intended given the help of his mother was FOR REAL....
Genesis 27:41 And Esau hated Jacob because of the blessing wherewith his father blessed him: and Esau said in his heart, “The days of mourning for my father are at hand; then will I slay my brother Jacob.”
And once again Rebekah was told and she sent Jacob away for his safety.
I think this notion of it being Esau's guardian angel that contended with Jacob and then changed Jacob's name to Israel is more than mixed up given the whole story.
‘The Mesorah’ is the explanation for the text that Moses transmitted from God to succeeding generations.
Someone reading the texts from Harvard Law without attending lectures and doing homework doesn’t have the whole story.
