God sent so many prophets to the Jewish people and protected them with much love, solely so that on that foundation after subjugating Satan, He could send them the Messiah, who is the fruit of the providence and the personification of the temple.
The tradition established by Jacob's subjugating Esau was to enable the people of Israel to fulfill Cain's position. Representing and taking responsibility on behalf of all mankind, they were to love, obey and serve the Messiah who was to come as the Abel for all the people.
