(20) Because the Lord thy God brought it to me.—Jacob does not keep up his acting well here, for it was not in accordance with Esau’s character to see anything providential in his success in hunting. This may have helped to arouse Isaac’s suspicions, who immediately proceeds to examine him.

Genesis 27:20. The Lord thy God brought it to me — Is this Jacob? It is certainly written not for our imitation, but our admonition. Here we see how one lie draws on another. Let him that standeth, take heed lest he fall.

Now let us see how Isaac gave Jacob his blessing.

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.Rebekah forms a plan for diverting the blessing from Esau to Jacob. She was within hearing when the infirm Isaac gave his orders, and communicates the news to Jacob. Rebekah has no scruples about primogeniture. Her feelings prompt her to take measures, without waiting to consider whether they are justifiable or not, for securing to Jacob that blessing which she has settled in her own mind to be destined for him. She thinks it necessary to interfere that this end may not fail of being accomplished. Jacob views the matter more coolly, and starts a difficulty. He may be found out to be a deceiver, and bring his father's curse upon him. Rebekah, anticipating no such issue; undertakes to bear the curse that she conceived would never come. Only let him obey.

Verse 14-29

The plan is successful. Jacob now, without further objection, obeys his mother. She clothes him in Esau's raiment, and puts the skins of the kids on his hands and his neck. The camel-goat affords a hair which bears a great resemblance to that of natural growth, and is used as a substitute for it. Now begins the strange interview between the father and the son. "Who art thou, my son?" The voice of Jacob was somewhat constrained. He goes, however, deliberately through the process of deceiving his father. "Arise, now, sit and eat." Isaac was reclining on his couch, in the feebleness of advancing years. Sitting was the posture convenient for eating. "The Lord thy God prospered me." This is the bold reply to Isaac's expression of surprise at the haste with which the dainty fare had been prepared. The bewildered father now puts Jacob to a severer test. He feels him, but discerns him not. The ear notes a difference, but the hand feels the hairy skin resembling Esau's; the eyes give no testimony. After this the result is summarily stated in a single sentence, though the particulars are yet to be given. "Art thou my very son Esau?" A lurking doubt puts the definite question, and receives a decisive answer. Isaac then calls for the repast and partakes.

18-27. he came unto his father—The scheme planned by the mother was to be executed by the son in the father's bedchamber; and it is painful to think of the deliberate falsehoods, as well as daring profanity, he resorted to. The disguise, though wanting in one thing, which had nearly upset the whole plot, succeeded in misleading Isaac; and while giving his paternal embrace, the old man was roused into a state of high satisfaction and delight. No text from Poole on this verse.

And Isaac said unto his son,.... Supposing him to be Esau:

how is it that thou hast found it so quickly, my son? that is, the venison; that he had met with it so soon in, the field, and got it dressed and ready in so short a time, which was not common, and seemed to be too little for doing all this in it, and so still created some suspicion of deceit:

and he said, because the Lord thy God brought it to me; which was another falsehood; for it was not the Lord, but his mother brought it to him: and this seems to be the most marvellous of all, that so good a man should dare to bring the name of the Lord God into this affair; indeed he does not say the Lord my God, or our God, but thy God; which some think was done on purpose, the more to cover the deceit, because they suppose that Esau, whom Jacob impersonated, was an idolater, but this is not so evident; rather it looks as if Jacob had not the confidence to call the Lord his God with a lie in his mouth.

And Isaac said unto his son, How is it that thou hast found it so quickly, my son? And he said, Because the LORD thy God brought it to me.
