18 So Jacob took the food to his father. "My father?" he said. "Yes, my son," Isaac answered. "Who are you-Esau or Jacob?" 19 Jacob replied, "It's Esau, your firstborn son. I've done as you told me. Here is the wild game. Now sit up and eat it so you can give me your blessing." 20 Isaac asked, "How did you find it so quickly, my son?" "The Lord your God put it in my path!" Jacob replied. 21 Then Isaac said to Jacob, "Come closer so I can touch you and make sure that you really are Esau." 22 So Jacob went closer to his father, and Isaac touched him. "The voice is Jacob's, but the hands are Esau's," Isaac said. 23 But he did not recognize Jacob, because Jacob's hands felt hairy just like Esau's. So Isaac prepared to bless Jacob. 24 "But are you really my son Esau?" he asked. "Yes, I am," Jacob replied. 25 Then Isaac said, "Now, my son, bring me the wild game. Let me eat it, and then I will give you my blessing." So Jacob took the food to his father, and Isaac ate it. He also drank the wine that Jacob served him. 26 Then Isaac said to Jacob, "Please come a little closer and kiss me, my son." 27 So Jacob went over and kissed him. And when Isaac caught the smell of his clothes, he was finally convinced, and he blessed his son. He said, "Ah! The smell of my son is like the smell of the outdoors, which the Lord has blessed! 28 "From the dew of heaven and the richness of the earth, may God always give you abundant harvests of grain and bountiful new wine. 29 May many nations become your servants, and may they bow down to you. May you be the master over your brothers, and may your mother's sons bow down to you. All who curse you will be cursed, and all who bless you will be blessed."
30 As soon as Isaac had finished blessing Jacob, and almost before Jacob had left his father, Esau returned from his hunt. 31 Esau prepared a delicious meal and brought it to his father. Then he said, "Sit up, my father, and eat my wild game so you can give me your blessing." 32 But Isaac asked him, "Who are you?" Esau replied, "It's your son, your firstborn son, Esau." 33 Isaac began to tremble uncontrollably and said, "Then who just served me wild game? I have already eaten it, and I blessed him just before you came. And yes, that blessing must stand!" 34 When Esau heard his father's words, he let out a loud and bitter cry. "Oh my father, what about me? Bless me, too!" he begged.

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.
