Genesis 27:24

Art thou my very son Esau? Isaac’s sense of touch must have been seriously affected by his infirmity or by his age. On the other hand, his sense of hearing was more acute, and made him suspicious of Jacob’s voice. But the scent of field and forest upon Esau’s garments (v. 15) seemed to confirm the touch of his son’s hairy hands. Finally, the fragrant aroma of “savoury meat” (v. 9) whetted his appetite, and he dismissed his fears. He could not see; but touch, taste, and smell prevailed over hearing. The original mistake that had led to this deception was Isaac’s own. Furthermore, he had deliberately gone forward with his plan to invest Esau with the birthright in the face of a divine command to the contrary, and God therefore permitted him to be deceived (see 1 Sam. 28:6; 1 Kings 14:1-6; Acts 5:1-11).
