Jacob Wrestling With Angel

When Yakov (Jacob) crossed the Yabok River,
which has deep mystical implications.
he encountered the Angel of Eisav (Esau),
with whom he wrestled the entire night
of the symbolic Galut גלות
and mundane consciousness.
At the redeeming “Dawn” גאולה
the Angel conceded
the battle and from then on
Jacob was called Israel ישראל
(which can be read in Hebrew,
ישר א-ל Direct to G-d)
the highest spiritual connection.
(Genesis 32:26
