Kabbalah sobre Génesis 27:31

"And he also had made savory food...Let my father arise" (Beresheet 27:31). His speech was impertinent, rough, and impolite. Come and behold the difference between Jacob and Esau. Jacob talked to his father humbly, with humility. It is written, "And he came to his father, and said, My father" (Ibid. 18). The difference between the language of Esau and Jacob is that Jacob did not want to frighten him. Thus, he spoke humbly, saying "arise, I pray you, sit and eat of my venison." Esau, however, said "Let my father arise," as if he was not speaking to him.
