ייִדישער מחשבֿה אויף בראשית 28:21

Some difficulties in the text of our Parshah: 1) Why did Jacob salute Esau with such excessive humility? Why the repeated obsequious references to "to find favor in your eyes?" 2) Why is the Torah silent about the manner in which Jacob's messengers carried out their mission? Why do the sages disagree as to the identity of those messengers? 3) What was the point of dividing the camps when Jacob's own family was part of the first camp? 4) If Jacob believed that the promises made to him by G-d on previous occasions were valid now, why did he fear the encounter? 5) When Jacob listed G-d’s promises, why did he not mention the promise in the dream with the ladder? 6) Why did Jacob instruct each of the gift-bearers to Esau separately? 7) Why did the angel that wrestled with Jacob insist on being released? 8) If the sun "shone for him," why would Jacob's limp be mentioned at this juncture? 9) What is the difference between "I have everything" (Jacob), and "I have a great deal" (Esau)? What is Esau's offer to accompany Jacob, and Jacob's polite refusal, all about?
