Pensée juive sur L’Exode 21:17

So far then Jacob's efforts provided him with useful information about how to approach Esau when he would meet him. Jacob's fear did not concern his own death at the hands of Esau, but he was concerned about the possible death of members of his family, concerning whom no promise from G-d had been received. The wording of the promise at Bet El in the dream of the ladder, had been directed only at Jacob alone. (3) Jacob divided the camp so that he could not be faulted for having neglected a chance to ensure partial survival. No doubt, the camp mentioned last, was positioned in such a way that Esau would encounter it first. Should Esau want to vent his rage by destroying Jacob's camp, and his anger could be assuaged by such a pogrom, Jacob's stratagem would have worked since that camp contained no one especially dear to him. If there had been only one camp and that had been attacked, all might have been lost. Jacob's prayer at that point acknowledged both the assistance received thus far and the promises made; it made the point however that all G-d’s promises made to Abraham and Isaac would come to nought if he and his family were not saved at this time. Jacob indicated that he did not think that he personally had any merit to entitle him to ask for favors for himself, seeing that when he had first set out on his quest he had only had a walking staff to call his own, and he had received so many favors from G-d that he was a wealthy man by now. He appealed for help, since, though assured of victory, in a battle involving so many, even victory might involve heavy casualties. G-d had not yet promised that no harm would come to any of them. Jacob was certainly entitled to feel alarmed at that point in his life. At the conclusion of his prayer, he looked for a sign that his prayer had received a favorable hearing. This is why he chose to spend the night at the site where he had offered his prayer. Since Jacob's efforts to save himself had not yet included a financial sacrifice, G-d withheld reassurance until he had done his share in that respect. It was the absence of a response from G-d then that galvanized Jacob into rising early on the following morning to arrange for the gifts to be sent to Esau. There are times when preoccupation with worldly matters-- which are after all only our second most important concerns-- exceeds what is reasonable and is apt to be misinterpreted. Jacob's encounter with the spiritual counterpart of Esau is an example of this. Since Jacob had risen during the night in order to carry insignificant belongings across the river Yabbok, this had been misinterpreted by Esau's guardian angel as evidence that Jacob was excessively concerned with worldly goods. This provided said angel with the opportunity to challenge Jaob's moral superiority over Esau (Chullin 91). Jacob recovered quickly enough from this momentary lapse, and the angel had to acknowledge Jacob's claim to morally high standards, by revealing to him that he would henceforth be known as "Israel." Nonetheless, the momentary weakness displayed and referred to by the Torah euphemistically as "dislocation of the hip joint," is frequently found among Jacob's descendants, and gives Esau/Amalek opportunities to attack the Jewish people's claim to moral leadership. Already Isaac had warned against this weakness in his blessing to Esau, when he told the latter, that he, Esau, would be able to shake off the yoke of his younger brother whenever the latter would fail to live up to his standards (Genesis 27,41). (7) The angel's request to let him go, is simply another way of saying to Jacob, "Why do you waste your time detaining me, when you should be busy preparing gifts for Esau."
