Genesis 27:26

He gives the kiss of paternal affection, and pronounces the benediction. It contains, first, a fertile soil. "Of the dew of heaven." An abundant measure of this was especially precious in a country where the rain is confined to two seasons of the year. "Of the fatness of the earth;" a proportion of this to match and render available the dew of heaven. "Corn and wine," the substantial products, implying all the rest. Second, a numerous and powerful offspring. "Let peoples serve thee" - pre-eminence among the nations. "Be lord of thy brethren" - pre-eminence among his kindred. Isaac does not seem to have grasped the full meaning of the prediction, "The older shall serve the younger." Third, Prosperity, temporal and spiritual. He that curseth thee be cursed, and he that blesseth thee be blessed. This is the only part of the blessing that directly comprises spiritual things; and even this of a special form. It is to be recollected that it was Isaac's intention to bless Esau, and he may have felt that Esau, after all, was not to be the progenitor of the holy seed. Hence, the form of expression is vague enough to apply to temporal things, and yet sufficiently comprehensive to embrace the infliction of the ban of sin, and the diffusion of the blessing of salvation by means of the holy seed.
