Esau and Jacob were twin sons of Isaac. But Esau was born first; and this, according to the law of primogeniture in that day, gave him special privileges, among which was the right on his part to a double portion of the heritage to be received from the father.
This right Jacob treacherously bought of his brother Esau. Rebekah, their mother, was favorable to the contract, and laid the plan for its successful completion. Esau had been unsuccessful in his pursuit of game, and soon found himself in a famishing condition. Jacob took advantage of this, and proposed to purchase the birthright. He said to Esau: "Sell me this day thy birthright." And Esau said: "Behold, I am at the point to die; and what profit shall this birthright do to me?" And he sold his birthright to Jacob. "Then Jacob gave Esau bread and a mess of lentiles; and he did eat and drink, and rose up and went his way: thus Esau despised his birthright."
Esau is here regarded as a profane or wicked person, because he did not more highly esteem the blessing to which he was born. Paul refers to this fact, to teach us that it is our duty, as the regenerated or "firstborn" children of God, to place a very high value upon our relation to him conferred by this birth.
"Esau found no place of repentance, though he sought it carefully with tears." This means that all his sorrow or regret for the foolish bargain he had made would not and could not place him back where he was before. The blessing of his father had been given to another past all possibility of calling it back. I do not, and can not, however, as some do, apply this to the sin against the Holy Ghost. The blessing of Jacob was all external. It comprehended only earthly things. I will read it, so that you may hear it: "God give thee of the dew of heaven, and the fatness of the earth, and plenty of corn and wine: 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." There is nothing in all this giving Jacob any claim to special favor from God, beyond that of mere earthly good. Neither does the sale of the birthright exclude Esau from any higher claim. He did not sell his right to serve the Lord, and thus inherit a heavenly blessing.
