Verse 35. - And he (i.e. Isaac) said, Thy brother came with subtlety, - with wisdom (Onkelos); rather with fraud, μετά δόλου (LXX.) - and hath taken away thy blessing - i.e. the blessing which I thought was thine, since Isaac now understood that from the first it had been designed for Jacob.

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.And he said, thy brother came with subtilty,.... The Targums of Onkelos and Jonathan, and so Jarchi, interpret it, "with wisdom", taking it in a good sense, and as excusing the fact; or rather commending it, as if it was wisely and prudently managed; but the word signifies fraud and deceit, and so it must be understood; though it may be Isaac says this, not so much to blame Jacob for what he had done, as to excuse himself to Esau, that he did not intend to give the blessing from him, but that he was imposed upon through the craft and subtilty of his brother, who feigned himself to be Esau; pretending he had been hunting, and had had wonderful success, and had got venison, and had prepared it; and came with goat, skins upon his hands and neck, that he might seem to be hairy as Esau was, and by these artful tricks he had deceived him, and therefore Esau could not blame him for what he had done:

and hath taken away thy blessing; which belonged to him as the firstborn, and he expected to have, and Isaac intended to have given it to him.
