Observe here, I. The art and assurance with which Jacob managed this intrigue. Who would have thought that this plain man could have played his part so well in a design of this nature? His mother having put him in the way of it, and encouraged him in it, he dexterously applied himself to those methods which he had never accustomed himself to, but had always conceived an abhorrence of. Note, Lying is soon learnt. The psalmist speaks of those who, as soon as they are born, speak lies, Psa 58:3; Jer 9:5. I wonder how honest Jacob could so readily turn his tongue to say (Gen 27:19), I am Esau thy first-born; nor do I see how the endeavour of some to bring him off with that equivocation, I am made thy first-born, namely by purchase, does him any service; for when his father asked him (Gen 27:24), Art thou my very son Esau? he said, I am. How could he say, I have done as thou badest me, when he had received no command from his father, but was doing as his mother bade him? How could he say, Eat of my venison, when he knew it came, not from the field, but from the fold? But especially I wonder how he could have the assurance to father it upon God, and to use his name in the cheat (Gen 27:20): The Lord thy God brought it to me. Is this Jacob? Is this Israel indeed, without guile? It is certainly written, not for our imitation, but for our admonition. Let him that thinks he stands take heed lest he fall. Good men have sometimes failed in the exercise of those graces for which they have been most eminent.
II. The success of this management. Jacob with some difficulty gained his point, and obtained the blessing.
1. Isaac was at first dissatisfied, and would have discovered the fraud if he could have trusted his own ears; for the voice was Jacob's voice, Gen 27:22. Providence has ordered a strange variety of voices as well as faces, which is also of use to prevent our being imposed upon; and the voice is a thing not easily disguised nor counterfeited. This may be alluded to to illustrate the character of a hypocrite. His voice is Jacob's voice, but his hands are Esau's. He speaks the language of a saint, but does the works of a sinner; but the judgement will be, as here, by the hands.
2. At length he yielded to the power of the cheat, because the hands were hairy (Gen 27:23), not considering how easy it was to counterfeit that circumstance; and now Jacob carries it on dexterously, sets his venison before his father, and waits at table very officiously, till dinner is done, and the blessing comes to be pronounced in the close of this solemn feast. That which in some small degree extenuates the crime of Rebekah and Jacob is that the fraud was intended, not so much to hasten the fulfilling, as to prevent the thwarting, of the oracle of God: the blessing was just going to be put upon the wrong head, and they thought it was time to bestir themselves. Now let us see how Isaac gave Jacob his blessing, Gen 27:26-29. (1.) He embraced him, in token of a particular affection to him. Those that are blessed of God are kissed with the kisses of his mouth, and they do, by love and loyalty, kiss the Son, Psa 2:12. (2.) He praised him. He smelt the smell of his raiment, and said, See, the smell of my son is as the smell of a field which the Lord hath blessed, that is, like that of the most fragrant flowers and spices. It appeared that God had blessed him, and therefore Isaac would bless him. (3.) He prayed for him, and therein prophesied concerning him. It is the duty of parents to pray for their children, and to bless them in the name of the Lord. And thus, as well as by their baptism, to do what they can to preserve and perpetuate the entail of the covenant in their families. But this was an extraordinary blessing; and Providence so ordered it that Isaac should bestow it upon Jacob ignorantly and by mistake, that it might appear he was beholden to God for it, and not to Isaac. Three things Jacob is here blessed with: - [1.] Plenty (Gen 27:28), heaven and earth concurring to make him rich. [2.] Power (Gen 27:29), particularly dominion over his brethren, namely, Esau and his posterity. [3.] Prevalency with God, and a great interest in Heaven: "Cursed by every one that curseth thee and blessed be he that blesseth thee. Let God be a friend to all thy friends, and an enemy to all they enemies." More is certainly comprised in this blessing than appears prima facie - at first sight. It must amount to an entail of the promise of the Messiah, and of the church; this was, in the patriarchal dialect, the blessing: something spiritual, doubtless, is included in it. First, That from him should come the Messiah, who should have a sovereign dominion on earth. It was that top-branch of his family which people should serve and nations bow down to. See Num 24:19, Out of Jacob shall come he that shall have dominion, the star and sceptre, Gen 27:17. Jacob's dominion over Esau was to be only typical of this, Gen 49:10. Secondly, That from him should come the church, which should be particularly owned and favoured by Heaven. It was part of the blessing of Abraham, when he was first called to be the father of the faithful (Gen 12:3), I will bless those that bless thee; therefore, when Isaac afterwards confirmed the blessing to Jacob, he called it the blessing of Abraham, Gen 28:4. Balaam explains this too, Num 24:9. Note, It is the best and most desirable blessing to stand in relation to Christ and his church, and to be interested in Christ's power and the church's favours.

I am Esau thy first-born - Here are many palpable falsehoods, and such as should neither be imitated nor excused. "Jacob," says Calmet, "imposes on his father in three different ways. 1. By his words: I am thy first-born Esau. 2. By his actions; he gives him kids' flesh for venison, and says he had executed his orders, and got it by hunting. 3. By his clothing; he puts on Esau's garments, and the kids' skins upon his hands and the smooth of his neck. In short, he made use of every species of deception that could be practiced on the occasion, in order to accomplish his ends." To attempt to palliate or find excuses for such conduct, instead of serving, disserves the cause of religion and truth. Men have labored, not only to excuse all this conduct of Rebekah and Jacob, but even to show that it was consistent, and that the whole was according to the mind and will of God!
Non tali auxilio,
non defensoribus istis
The cause of God and truth is under no obligation to such defenders; their hands are more unhallowed than those of Uzzah; and however the bearers may stumble, the ark of God requires not their support. It was the design of God that the elder should serve the younger, and he would have brought it about in the way of his own wise and just providence; but means such as here used he could neither sanction nor recommend.

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.

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.
