The promise to Jacob

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.

Genesis 28:1-5

So Isaac called for Jacob and blessed him. Then he commanded him: “Do not marry a Canaanite woman. ² Go at once to Paddan Aram, to the house of your mother’s father Bethuel. Take a wife for yourself there, from among the daughters of Laban, your mother’s brother. ³ May God Almightybless you and make you fruitful and increase your numbers until you become a community of peoples. ⁴ May he give you and your descendants the blessing given to Abraham, so that you may take possession of the land where you now reside as a foreigner, the land God gave to Abraham.” ⁵ Then Isaac sent Jacob on his way, and he went to Paddan Aram, to Laban son of Bethuel the Aramean, the brother of Rebekah, who was the mother of Jacob and Esau.
