And Isaac trembled - The marginal reading is very literal and proper, And Isaac trembled with a great trembling greatly. And this shows the deep concern he felt for his own deception, and the iniquity of the means by which it had been brought about. Though Isaac must have heard of that which God had spoken to Rebekah, The elder shall serve the younger, and could never have wished to reverse this Divine purpose; yet he might certainly think that the spiritual blessing might be conveyed to Esau, and by him to all the nations of the earth, notwithstanding the superiority of secular dominion on the other side.

Yea, and he shall be blessed - From what is said in this verse, collated with Hebrews 12:17, we see how binding the conveyance of the birthright was when communicated with the rites already mentioned. When Isaac found that he had been deceived by Jacob, he certainly would have reversed the blessing if he could; but as it had been conveyed in the sacramental way this was impossible. I have blessed him, says he, yea, and he must, or will, be blessed. Hence it is said by the apostle. Esau found no place for repentance, μετανοιας γαρ τοπον ουχ εὑρε, no place for change of mind or purpose in his father, though he sought it carefully with tears. The father could not reverse it because the grant had already been made and confirmed. But this had nothing to do with the final salvation of poor outwitted Esau, nor indeed with that of his unnatural brother.

And Isaac trembled very exceedingly,.... Or "trembled with a great trembling exceedingly" (b); he was amazed, and astonished, and seized with a trembling all over his body, and with terror and confusion of mind; at the craft of Jacob in getting the blessing; at the disappointment of Esau in losing it; at his own act in blessing Jacob instead of Esau, contrary to his inclination and intention; and at the overruling providence of God in bringing this about in so strange a manner, agreeably to the oracle he had given Rebekah; which now perhaps came fresh into the mind of Isaac, if he had heard it before; and all together threw him into this amazement:

and he said, who? where is he; which words spoken in haste, and without order, show the hurry and consternation of mind he was in:

that hath taken venison, and brought it me, and I have eaten of all before thou camest; he was here but just now; he was scarce gone out before thou camest in; who, and where is he, that has done this? He knew it must be Jacob that had prepared and brought him food he called venison, which he had eaten sufficiently of, though in the confusion of his mind he puts these questions: and

have blessed him? yea, and he shall be blessed; for he now saw clearly that it was according to the divine will that Jacob should be blessed, though his natural affection led him to bless Esau; and no doubt, while he was pronouncing the blessing on Jacob, he felt an uncommon impulse upon his mind, by which he was assured that he was right in blessing him, that it was according to the will of God, was by his direction, and with his approbation; and therefore he here, even after Jacob's deceit was detected, confirms and ratifies it; and this is added, lest any question should be made of the validity of the blessing of Jacob, when it was given through mistake, and got by deceit; but this Isaac did and said knowingly, and by faith, as the apostle says, Hebrews 11:20.

(b) "contremuit tremore magno usque valde", Montanus; Pagninus, Schmidt.

And Isaac {f} trembled very exceedingly, and said, Who? where is he that hath taken venison, and brought it me, and I have eaten of all before thou camest, and have blessed him? yea, and he shall be blessed.

(f) In perceiving his error, by appointing his heir against God's sentence pronounced before.

27:33 Isaac trembled exceedingly - Those that follow the choice of their own affections rather than the dictates of the Divine will, involve themselves in such perplexities as these. But he soon recovers himself, and ratifies the blessing he had given to Jacob, I have blessed him, and he shall be blessed - He might have recalled it, but now at last he is sensible he was in an error when he designed it for Esau. Either recollecting the Divine oracle, or having found himself more than ordinarily filled with the Holy Ghost when he gave the blessing to Jacob, he perceived that God did as it were say Amen to it.

trembled...: Heb. trembled with a great trembling greatly

taken: Heb. hunted

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.
