Chasidut su Genesi 27:28

Genesis 32,4. “I have remained a stranger at ‎Lavan’s” (all the time); my late father of blessed memory, ‎commented on Rashi’s interpretation of Yaakov having ‎chosen the word ‎גרתי‎, that he referred to the numerical value of ‎the letters in this word being 613, a symbol of the 613 ‎commandments of the Torah that Yaakov observed even while in ‎Padan Aram. He supposedly emphasized to Esau that in spite of ‎his having acquired considerable wealth, none of it had been at ‎the expense of Esau, as his father’s blessing which was: “may the ‎Lord give you from the dew of heaven and the fat parts of the ‎earth” (Genesis 27,28) had not been fulfilled. Should Esau counter ‎that the reason Yitzchok’s blessing had not been fulfilled was that ‎he, Yaakov, had not observed the commandments, this was not ‎so. Esau knew that his father’s blessings were conditional on a ‎certain mode of conduct by Yaakov, and that is why he had told ‎him (Genesis 27,40) ‎והיה כאשר תריד ופרקת עול מעל צוארך‎, (according ‎to Rashi) “if the Israelites will fail to observe the ‎commandment, you will be able to shake off his yoke from your ‎neck.” Yaakov hints to his brother that in spite of having ‎observed the commandments he does not own any land, so that ‎his father’s blessings could not have been fulfilled. Yaakov ‎reassures Esau that he has no reason to revenge himself for ‎Yaakov having obtained this blessing.‎

Genesis 27,28. “and may the Lord give you of the dew ‎of heaven and an abundance of grain, etc.” This line is best ‎understood in accordance with the Talmud [source not ‎found Ed.]. Parnassah, usually translated as ‎livelihood, “economic well being,” is understood as a pleasurable ‎experience, ‎תענוג‎, i.e. the service performed by the Jewish people ‎for G’d results in a satisfying experience for the Lord. The reason ‎that the Lord desires for Israel to serve Him and the resulting ‎satisfaction is known as ‎דלת‎, a word derived from ‎דלה ועניה‎, ‎poverty, inadequacy. Just as a poor man constantly feels in need, ‎so G’d constantly feels the desire to be served by His creatures. By ‎doing so, they provide Him with what in our parlance is “a ‎livelihood.” [I have paraphrased this. Ed.]‎
