27:33 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.
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.
