30 It happened, as soon as Isaac had made an end of blessing Jacob, and Jacob had just gone out from the presence of Isaac his father, that Esau his brother came in from his hunting. 31 He also made savory food, and brought it to his father. He said to his father, “Let my father arise, and eat of his son’s venison, that your soul may bless me.” 32 Isaac his father said to him, “Who are you?”

He said, “I am your son, your firstborn, Esau.” 33 Isaac trembled violently, and said, “Who, then, is he who has taken venison, and brought it me, and I have eaten of all before you came, and have blessed him? Yes, he will be blessed.” 34 When Esau heard the words of his father, he cried with an exceeding great and bitter cry, and said to his father, “Bless me, even me also, my father.” 35 He said, “Your brother came with deceit, and has taken away your blessing.” 36 He said, “Isn’t he rightly named Jacob? For he has supplanted me these two times. He took away my birthright. See, now he has taken away my blessing.” He said, “Haven’t you reserved a blessing for me?” 37 Isaac answered Esau, “Behold, I have made him your lord, and all his brothers have I given to him for servants. With grain and new wine have I sustained him. What then will I do for you, my son?” 38 Esau said to his father, “Have you but one blessing, my father? Bless me, even me also, my father.” Esau lifted up his voice, and wept. 39 Isaac his father answered him,

“Behold, of the fatness of the earth will be your dwelling,
and of the dew of the sky from above. 40 By your sword will you live, and you will serve your brother.
It will happen, when you will break loose,
that you shall shake his yoke from off your neck.”

Commentary on Genesis 27:30-40

(Read Genesis 27:30-40)

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.
