18 So he went in to his father, and said, "My father"; and he said, "Here I am; who are you, my son?" 19 Jacob said to his father, "I am Esau your firstborn. I have done as you told me; now sit up and eat of my game, so that you may bless me." 20 But Isaac said to his son, "How is it that you have found it so quickly, my son?" He answered, "Because the Lord your God granted me success." 21 Then Isaac said to Jacob, "Come near, that I may feel you, my son, to know whether you are really my son Esau or not." 22 So Jacob went up to his father Isaac, who felt him and said, "The voice is Jacob's voice, but the hands are the hands of Esau." 23 He did not recognize him, because his hands were hairy like his brother Esau's hands; so he blessed him. 24 He said, "Are you really my son Esau?" He answered, "I am." 25 Then he said, "Bring it to me, that I may eat of my son's game and bless you." So he brought it to him, and he ate; and he brought him wine, and he drank. 26 Then his father Isaac said to him, "Come near and kiss me, my son." 27 So he came near and kissed him; and he smelled the smell of his garments, and blessed him, and said, "Ah, the smell of my son is like the smell of a field that the Lord has blessed. 28 May God give you of the dew of heaven, and of the fatness of the earth, and plenty of grain and wine. 29 Let peoples serve you, and nations bow down to you. Be lord over your brothers, and may your mother's sons bow down to you. Cursed be everyone who curses you, and blessed be everyone who blesses you!"
30 As soon as Isaac had finished blessing Jacob, when Jacob had scarcely gone out from the presence of his father Isaac, his brother Esau came in from his hunting. 31 He also prepared savory food, and brought it to his father. And he said to his father, "Let my father sit up and eat of his son's game, so that you may bless me." 32 His father Isaac said to him, "Who are you?" He answered, "I am your firstborn son, Esau." 33 Then Isaac trembled violently, and said, "Who was it then that hunted game and brought it to me, and I ate it all before you came, and I have blessed him?-yes, and blessed he shall be!" 34 When Esau heard his father's words, he cried out with an exceedingly great and bitter cry, and said to his father, "Bless me, me also, father!"

Commentary on Genesis 27:18-29
(Read Genesis 27:18-29)
Jacob, with some difficulty, gained his point, and got the blessing. This blessing is in very general terms. No mention is made of the distinguishing mercies in the covenant with Abraham. This might be owing to Isaac having Esau in his mind, though it was Jacob who was before him. He could not be ignorant how Esau had despised the best things. Moreover, his attachment to Esau, so as to disregard the mind of God, must have greatly weakened his own faith in these things. It might therefore be expected, that leanness would attend his blessing, agreeing with the state of his mind.
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.
