Matthew Poole and continuators on Genesis 27:33

33 And Isaac 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 .

He was filled with astonishment and horror in consideration of Iacobs fraud, and the sad disappointment and great Misery of his beloved Esau, and his own rashness and folly in suffering his fond affection towards him to carry him headlong into an opposition to the Divine Oracle, Gen. 25. 23. which now came to his remembrance, as appears by his ratification of Iacobs blessing.

A short speech proceeding from a discomposed mind.

This blessing, though otherwise intended by me, and pronounced upon a mistake of the person, shall and must rest upon the head of Iacob, and I neither can nor dare undertake to revoke and contradict Gods appointment, which now I more fully discern, and in which both thou and I and all men must fully acquiesce. And now Isaac fixeth the blessing upon Iacob by faith, as it is expressed, Heb. 11. 20. which before through misguided Fancy and Affection he intended for Esau.
