I'm sure most of us have heard how this incident is always a comparison to Gethsemane
Christ wrestles with His Father & his fleshly will (or something like that) - to come out the Victor (Israel meaning He has striven with God and Man and wins)
Now if we continue to take Esau as Adam - then the story continues
as much as Jacob's 'mission' was to present Esau to the Father (Isaac)
now after the wrestling - Jacob is prepared to reconcile with horrible Esau who (he thinks) has come to murder Him
and in some sense - there ends the story of Jacob?
(read bit of this in someone's quotations from Chrysostom)
