Genesis 27:29

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. This part of the blessing describes the position of influence and power which the descendants of Jacob were to occupy. Not only over his brethren, over the people of his own race, including the children of his brother, he was to be lord, but also over strange people and nations. The idea of a world dominion is thus brought out, culminating in the promise that men would be judged according to their attitude toward him and his descendants. Thus the blessing looks forward to the Messiah, the touchstone of the ages, for to this day the right answer to the question: What think ye of Christ? decides the fate of every person in the world.
