Let people serve thee (literally, and will serve thee, peoples; at once a prayer and a prophecy; fulfilled in the political subjection of the Moabites, Ammonites, Syrians, Philistines, and Edomites by David; the thought being repeated in the next clause), and nations bow down to thee (in expression of their homage): be lord over thy brethren,—literally, be a lord (from the idea of power; found only here and in Genesis 27:37) to thy brethren. Imminence among his kindred as well as dominion in the world is thus promised—and let thy mother's sons bow down to thee (a repetition of the preceding thought, with perhaps a hint of his desire to humble Jacob, the favorite of Rebekah): cursed be every one that curseth thee, and blessed be he that blesseth thee—framed on the model of the Abrahamic benediction (Genesis 12:3); but not so full as that, either because Isaac felt that after all Esau was not to be the progenitor of the holy seed (Murphy), or because, not being actuated by proper feelings towards Jehovah and his promises, the patriarch could not rise to that height of spiritual benediction to which he afterwards attained—Genesis 28:3, Genesis 28:4 (Keil), or because the prerogative of pronouncing the Abrahamic blessing in all its fullness Jehovah may have reserved to himself, as in Genesis 28:14 ('Speaker's Commentary').
