28:1-5 Jacob had blessings promised both as to this world and that which is to come; yet goes out to a hard service. This corrected him for the fraud on his father. The blessing shall be conferred on him, yet he shall smart for the indirect course taken to obtain it. Jacob is dismissed by his father with a solemn charge. He must not take a wife of the daughters of Canaan: those who profess religion, should not marry with those that care not for religion. Also with a solemn blessing. Isaac had before blessed him unwittingly; now he does it designedly. This blessing is more full than the former; it is a gospel blessing. This promise looks as high as heaven, of which Canaan was a type. That was the better country which Jacob and the other patriarchs had in view.
Ge 28:1-19. Jacob's Departure.
1. Isaac called Jacob and blessed him—He entered fully into Rebekah's feelings, and the burden of his parting counsel to his son was to avoid a marriage alliance with any but the Mesopotamian branch of the family. At the same time he gave him a solemn blessing—pronounced before unwittingly, now designedly, and with a cordial spirit. It is more explicitly and fully given, and Jacob was thus acknowledged "the heir of the promise."
