37 Isaac said to Esau, "I have made Jacob your master and have declared that all his brothers will be his servants. I have guaranteed him an abundance of grain and wine-what is left for me to give you, my son?" 38 Esau pleaded, "But do you have only one blessing? Oh my father, bless me, too!" Then Esau broke down and wept. 39 Finally, his father, Isaac, said to him, "You will live away from the richness of the earth, and away from the dew of the heaven above. 40 You will live by your sword, and you will serve your brother. But when you decide to break free, you will shake his yoke from your neck."

When Esau understood that Jacob had got the blessing, he cried with a great and exceeding bitter cry. The day is coming, when those that now make light of the blessings of the covenant, and sell their title to spiritual blessings for that which is of no value, will, in vain, ask urgently for them. Isaac, when made sensible of the deceit practised on him, trembled exceedingly. Those who follow the choice of their own affections, rather than the Divine will, get themselves into perplexity. But he soon recovers, and confirms the blessing he had given to Jacob, saying, I have blessed him, and he shall be blessed. Those who part with their wisdom and grace, their faith and a good conscience, for the honours, wealth, or pleasures of this world, however they feign a zeal for the blessing, have judged themselves unworthy of it, and their doom shall be accordingly. A common blessing was bestowed upon Esau. This he desired. Faint desires of happiness, without right choice of the end, and right use of the means, deceive many unto their own ruin. Multitudes go to hell with their mouths full of good wishes. The great difference is, that there is nothing in Esau's blessing which points at Christ; and without that, the fatness of the earth, and the plunder of the field, will stand in little stead. Thus Isaac, by faith, blessed both his sons, according as their lot should be.
