Musar para sa Genesis 27:25

The sense of taste includes as its species four qualities, namely, Joy (Cheerfulness), Grief (Apprehensiveness), Penitence, and Tranquility. Dost thou not see that the greatest pleasure is derived through eating and drinking, which is attained by means of the sense of taste? Hast thou not heard of the saying on the part of Isaac (Gen. xxvii. 25), "Bring it here unto me and I will eat of my son's venison"; and also (Ruth iii. 7), "And when Boaz had eaten and drunk, his heart was merry." Speech, consisting as it does of words, which are of a kind with (the objects of) taste, sometimes gives rise to joy; thus it is said (Prov. xv. 23), "A man hath joy by the answer of his mouth." Opposed to this we find that grief follows upon the failure to exercise this sense, as it is said (i Sam. i. 7), "She wept and did not eat." It is also related of Jonathan (id. xx. 34), "He did eat no meat the second day of the month, for he was grieved for David." Many such expressions are used with reference to Saul and others.

The Torah reports Isaac as blessing Jacob immediately after Isaac smelled the fragrance of Paradise, i.e. ויברכהו. He did not investigate further, for in the event that it was indeed the real Esau, he was entitled to the blessings valid in this world, whereas in the event it was Jacob who stood before him, Isaac intended these blessings to apply in the Hereafter. This is in accordance with what I wrote at the beginning, that these blessings must be understood on two different levels. The word ויברכהו was the umbrella term for these blessings. Only afterwards did Isaac want to know who really stood in front of him. When the Torah describes Jacob as bringing wine from which Isaac drank (27,25), this is a reference to the "wine preserved in its grapes since the days of creation,” which will be served to the righteous in the Hereafter, as we have explained on several occasions.
