As the final moments of a patriarch's life approach, a profound shift occurs. A physical decline marks more than just the end of a long journey; it signals a critical juncture where a father prepares to pass his legacy and blessings to the next generation. Word reaches Joseph that his father is failing. The identity of the person who delivers this news is left unnamed. The primary approach among commentators is that this simply refers to an anonymous messenger who arrived to inform Joseph of the situation [אבן עזרא, רד״ק, רשב״ם]. However, another tradition suggests the messenger was actually Joseph's own son, Ephraim. Ephraim spent much of his time with Jacob, studying Torah, and when his grandfather fell ill, he immediately hurried to tell his father [רש״י, גור אריה].
The very fact that Joseph required a messenger and was not already at his father's bedside stems from a deep-seated fear. Joseph worried that if he stayed close, Jacob would eventually ask how he truly ended up in Egypt. Knowing that Jacob had once unknowingly cursed Rachel with fatal consequences, Joseph feared that revealing the brothers' betrayal would provoke a curse that could destroy the world. To prevent this, he chose to keep his distance [דעת זקנים, הדר זקנים].
The news of Jacob's illness carries a remarkable historical precedent. Illness itself represents a sudden halt in the natural movement and progress of life [רש״ר הירש]. Commentators agree that until Jacob's time, the concept of falling sick before passing away did not exist. People would die suddenly, often from a mere sneeze. It was Jacob who prayed and asked God for the mercy of physical decline. He requested that weakness be introduced into the world so that a person would receive an advance warning of their death, granting them the time to repent, part from their family, and leave instructions for their children. The sudden arrival of this condition marks the appearance of a completely new and unfamiliar phenomenon [תורה תמימה, שפתי כהן, חזקוני]. While Jacob had already experienced the natural weakness of old age, it now became perfectly clear to Joseph that this was a terminal illness from which his father would not recover [מזרחי, ביאור שטיינזלץ].
Upon hearing the news, Joseph rushed to bring his sons to Jacob to secure their grandfather's blessing before he passed. He deliberately brought both Manasseh and Ephraim to ensure each son would receive an independent and unique blessing, rather than merely being included as an extension of his own. The boys were worthy of this honor for two distinct reasons: their status as his sons and their own personal righteousness. Each son was considered significant and important in his own right [אור החיים]. Furthermore, Joseph made a point to bring Manasseh along, despite knowing that Ephraim was Jacob's favorite. He did this to ensure that Ephraim would not be the sole recipient of the grandfather's final blessing [ברכת אשר].
