In what way was Isaac's blessing on Jacob manifested?

In Genesis 27, when elderly Isaac thought he was blessing his son Esau, but he was actually blessing his son Jacob through the deceit of Jacob's mother, he said to Jacob: > See, the smell of my son is as the smell of a field which the LORD > hath blessed: Therefore God give thee of the dew of heaven, and the > fatness of the earth, and plenty of corn and wine: Let people serve > thee, and nations bow down to thee: be lord over thy brethren, and let > thy mother's sons bow down to thee: cursed be every one that curseth > thee, and blessed be he that blesseth thee (Genesis 27:27b-29). My Bible commentaries don't explain how this blessing was borne out. What do Protestant or Catholic authorities say about how this blessing was fulfilled in Jacob's life?
