Rabbi Haninah taught that Esau paid great attention to his parent ("horo"), his father, whom he supplied with meals, as reports, "Isaac loved Esau, because he ate of his venison." Rabbi Samuel the son of Rabbi Gedaliah concluded that God decided to reward Esau for this. When Jacob offered Esau gifts, Esau answered Jacob in , "I have enough (, "rav"); do not trouble yourself." So God declared that with the same expression that Esau thus paid respect to Jacob, God would command Jacob's descendants not to trouble Esau's descendants, and thus God told the Israelites in , "You have circled this mountain (, "har") long enough (, "rav")."
