Kabbalah su Genesi 25:34

Rabbi Yosi said, It is later written, "Then Jacob gave Esau bread and pottage of lentils" (Beresheet 25:34). What are these lentils? They are round as a circle, and as the circle which revolves around the world does not deviate from its path, so man in that time will never deviate from his. Although there will yet be all that is good and precious and perfect, with all that, the worldly habit of eating and drinking will not change.

He responded, Now you deserve a whipping, because you believed Esau and lied about Ya'akov's words. The scripture bears witness that "Jacob was a plain man" (Gen. 25:27), (i.e. he was unable to cheat). Also, it is written, "You will show truth to Jacob" (Michah 7:20). This was the situation concerning Jacob and Esau. Even before, Esau detested his birthright, and he asked Jacob to take the birthright without payment! Thus, it is as written, "and he did eat and drink, and rose up, and went his way, thus Esau despised the birthright" (Gen. 25:34).
