Genesis 27:5

Esau agreed to Isaac’s plan. In doing so, he broke the oath he had sworn to Jacob (25:33).

The blessing seemed to be at risk. In the second scene, Rebekah and Jacob tried to gain God’s blessing through deception, rather than through faith and love. Rebekah made a plan to trick Isaac, who was old, into thinking he was blessing Esau when he was actually blessing Jacob.

Jacob got his father Isaac’s blessing through deception. In this story, an entire family tries to carry out their responsibilities by physical means rather than by faith. Faith would have provided Rebekah and Jacob a more honorable solution to the crisis.

make . . . savory meat--perhaps to revive and strengthen him for the duty; or rather, "as eating and drinking" were used on all religious occasions, he could not convey the right, till he had eaten of the meat provided for the purpose by him who was to receive the blessing [ADAM CLARKE] (compare Gen 18:7).

that my soul may bless thee--It is difficult to imagine him ignorant of the divine purpose (compare Gen 25:23). But natural affection, prevailing through age and infirmity, prompted him to entail the honors and powers of the birthright on his elder son; and perhaps he was not aware of what Esau had done (Gen 25:34).

Here is, I. Isaac's design to make his will, and to declare Esau his heir. The promise of the Messiah and the land of Canaan was a great trust, first committed to Abraham, inclusive and typical of spiritual and eternal blessings; this, by divine direction, he transmitted to Isaac. Isaac, being now old, and not knowing, or not understanding, or not duly considering, the divine oracle concerning his two sons, that the elder should serve the younger, resolves to entail all the honour and power that were wrapped up in the promise upon Esau his eldest son. In this he was governed more by natural affection, and the common method of settlements, than he ought to have been, if he know (as it is probable he did) the intimations God had given of his mind in this matter. Note, We are very apt to take our measures rather from our own reason than from divine revelation, and thereby often miss our way; we think the wise and learned, the mighty and noble, should inherit the promise; but God sees not as man sees. See Sa1 16:6, Sa1 16:7.
II. The directions he gave to Esau, pursuant to this design. He calls him to him, Gen 27:1. For Esau, though married, had not yet removed; and, though he had greatly grieved his parents by his marriage, yet they had not expelled him, but it seems were pretty well reconciled to him, and made the best of it. Note, Parents that are justly offended at their children yet must not be implacable towards them.
1. He tells him upon what considerations he resolved to do this now (Gen 27:2): "I am old, and therefore must die shortly, yet I know not the day of my death, nor when I must die; I will therefore do that at this time which must be done some time." Note, (1.) Old people should be reminded by the growing infirmities of age to do quickly, and with all the little might they have, what their hand finds to do. See Jos 13:1. (2.) The consideration of the uncertainty of the time of our departure out of the world (about which God has wisely kept us in the dark) should quicken us to do the work of the day in its day. The heart and the house should both be set, and kept, in order, because at such an hour as we think not the son of man comes; because we know not the day of our death, we are concerned to mind the business of life.
2. He bids him to get things ready for the solemnity of executing his last will and testament, by which he designed to make him his heir, Gen 27:3, Gen 27:4. Esau must go a hunting, and bring some venison, which his father will eat of, and then bless him. In this he designed, not so much the refreshment of his own spirits, that he might give the blessing in a lively manner, as it is commonly taken, but rather the receiving of a fresh instance of his son's filial duty and affection to him, before he bestowed this favour upon him. Perhaps Esau, since he had married, had brought his venison to his wives, and seldom to his father, as formerly (Gen 25:28), and therefore Isaac, before he would bless him, would have him show this piece of respect to him. Note, It is fit, if the less be blessed of the greater, that the greater should be served and honoured by the less He says, That my soul may bless thee before I die. Note, (1.) Prayer is the work of the soul, and not of the lips only; as the soul must be employed in blessing God (Psa 103:1), so it must be in blessing ourselves and others: the blessing will not come to the heart if it do not come from the heart. (2.) The work of life must be done before we die, for it cannot be done afterwards (Ecc 9:10); and it is very desirable, when we come to die, to have nothing else to do but to die. Isaac lived above forty years after this; let none therefore think that they shall die the sooner for making their wills and getting ready for death.

And Rebekah heard. Moses now explains more fully the artifice by which Jacob attained the blessing. It truly appears ridiculous, that an old man, deceived by the cunning of his wife, should, through ignorance and error, have given utterance to what was contrary to his wish. And surely the stratagem of Rebekah was not without fault; for although she could not guide her husband by salutary counsel, yet it was not a legitimate method of acting, to circumvent him by such deceit. For, as a lie is in itself culpable, she sinned more grievously still in this, that she desired to sport in a sacred matter with such wiles. She knew that the decree by which Jacob had been elected and adopted was immutable; why then does she not patiently wait till God shall confirm it in fact, and shall show that what he had once pronounced from heaven is certain? Therefore, she darkens the celestial oracle by her lie, and abolishes, as far as she was able, the grace promised to her son. Now, if we consider farther, whence arose this great desire to bestir herself; her extraordinary faith will on the other hand appear. For, as she did not hesitate to provoke her husband against herself, to light up implacable enmity between the brothers, to expose her beloved son Jacob to the danger of immediate death, and to disturb the whole family; this certainly flowed from no other source than her faith. [42] The inheritance promised by God was firmly fixed in her mind; she knew that it was decreed to her son Jacob. And therefore, relying upon the covenant of God, and keeping in mind the oracle received, she forgets the world. Thus, we see, that her faith was mixed with an unjust and immoderate zeal. This is to be carefully observed, in order that we may understand that a pure and distinct knowledge does not always so illuminate the minds of the pious as to cause them to be governed, in all their actions, by the Holy Spirit, but that the little light which shows them their path is enveloped in various clouds of ignorance and error; so that while they hold a right course, and are tending towards the goal, they yet occasionally slide. Finally, both in Isaac and in his wife the principle of faith was preeminent. But each, by ignorance in certain particulars, and by other faults, either diverged a little from the way, or, at least, stumbled in the way. But seeing that, nevertheless, the election of God stood firm; nay, that he even executed his design through the deceit of a woman, he vindicates, in this manner, the whole praise of his benediction to his own gratuitous goodness.

And Rebekah heard - And was determined, if possible, to frustrate the design of Isaac, and procure the blessing for her favorite son. Some pretend that she received a Divine inspiration to the purpose; but if she had she needed not to have recourse to deceit, to help forward the accomplishment. Isaac, on being informed, would have had too much piety not to prefer the will of his Maker to his own partiality for his eldest son; but Rebekah had nothing of the kind to plead, and therefore had recourse to the most exceptionable means to accomplish her ends.

And Rebekah heard when Isaac spake to Esau his son,.... She might hear Isaac call to him by one means or another, that he had sent for him, or might see him go into his father's tent, and might stand at the door of it and listen to hear what he said to him; though the Targum of Jonathan says, she heard by the Holy Spirit:

and Esau went to the field to hunt for venison, and to bring it; as his father directed and enjoined him; and thus it was ordered by divine Providence, that there might be time and opportunity for Jacob to get the blessing before his broker.

Rebekah, who heard what he said, sought to frustrate this intention, and to secure the blessing for her (favourite) son Jacob. Whilst Esau was away hunting, she told Jacob to take his father a dish, which she would prepare from two kids according to his taste; and, having introduced himself as Esau, to ask for the blessing "before Jehovah." Jacob's objection, that the father would know him by his smooth skin, and so, instead of blessing him, might pronounce a curse upon him as a mocker, i.e., one who was trifling with his blind father, she silenced by saying, that she would take the curse upon herself. She evidently relied upon the word of promise, and thought that she ought to do her part to secure its fulfilment by directing the father's blessing to Jacob; and to this end she thought any means allowable. Consequently she was so assured of the success of her stratagem as to have no fear of the possibility of a curse. Jacob then acceded to her plan, and fetched the goats. Rebekah prepared them according to her husband's taste; and having told Jacob to put on Esau's best clothes which were with her in the dwelling (the tent, not the house), she covered his hands and the smooth (i.e., the smoother parts) of his neck with the skins of the kids of the goats,
(Note: We must not think of our European goats, whose skins would be quite unsuitable for any such deception. "It is the camel-goat of the East, whose black, silk-like hair was used even by the Romans as a substitute for human hair. Martial xii. 46." - Tuch on v. 16.)
and sent him with the savoury dish to his father.
