Musar su Genesi 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.
