The revolt of Edom demands our particular notice, because it was a confirmation of the dying patriarch Isaac's prophecy to his son Esau, who was the origin of Edom. Isaac had told his favorite son Esau, that the time should come when he should break Jacob's yoke from off his neck. And here we see it fulfilled after a servitude of more than 150 years from the days of David. Genesis 27:39-40.
