רבינו בחיי — ויירא יעקב מאד ויצר לו

Q — Why does Yaakov, upon hearing that Esav is approaching, prepare on three apparently contradictory fronts at once — splitting his camp for war, sending a lavish gift, and praying for deliverance?

A — Rabbeinu Bachya: this is not panic. It is a deliberate תקנה לשלשה דברים — מלחמה, תפלה, דורון — that Yaakov hands down as the template for every confrontation Klal Yisrael will have with the descendants of Esav until the end of history. Chizkiyahu followed the same playbook against Sancheriv (giving silver, posting officers, davening). The chiddush: galut requires all three simultaneously — never gift alone, never prayer alone, never sword alone. And after the שבועה of "השבעתי אתכם בנות ירושלים" in chu"l we lose access to milchama; what remains is the doron of soft speech and the tefillah. The narrative of Vayishlach is a שטר הוראה for how the descendants of Yaakov are to face Esav in every generation.
