בראשית, פרק מ״ח, פסוק ח׳

Moments before passing on the tradition and giving his final blessings to the next generation, an elderly grandfather looks at his grandsons, who had grown up near him in Egypt, and surprisingly asks for their identity. The primary approach among commentators focuses on the physical reality of his advanced age and failing eyesight. He could see the general shapes and silhouettes of people standing next to Joseph, but he could not make out their facial features to recognize them [רשב״ם, ספורנו, רד״ק, אבן עזרא, הטור הארוך, ביאור יש״ר]. It is also possible that much time had passed since their last meeting, and the boys had grown and changed. As a result, Jacob recognized Joseph by his voice but did not know his companions [חזקוני, ביאור שטיינזלץ]. Adding to the confusion, the young men might have been dressed in the official uniforms of Egyptian nobility, clothing that was entirely foreign to Jacob [מלבי״ם]. Fearing that strangers were standing in the room listening to his secrets, he asked for their identity [אברבנאל]. Alternatively, the boys simply may have been standing at a distance out of respect for him [שד״ל].

A deeper perspective views this encounter as a profound spiritual event, where the grandfather's sight was not physical, but rather a vision of the mind and prophecy [רבנו בחיי, שפתי חכמים]. As Jacob prepared to bless the young men, the Divine Presence suddenly departed from him. Looking into the future through the Holy Spirit, he saw the wicked kings who would eventually descend from them, specifically Jeroboam and Ahab from the tribe of Ephraim, and Jehu and his sons from the tribe of Manasseh. This prophetic vision, particularly the sight of the future golden calves, deeply shocked him. His question was therefore a reaction to this disturbing revelation, asking about the true nature of these boys and why they appeared unfit for a blessing [רש״י, רבנו בחיי, שפתי כהן, קונטרס חיבה יתירה, בעלי ברית אברם]. The departure of the Holy Spirit happened specifically with these grandsons, as opposed to Jacob's own sons who also had wicked descendants, because his direct merit did not protect the grandchildren with the same strength [ברטנורא]. Some suggest that Jacob felt the sudden loss of prophetic inspiration but did not understand why it happened, which only deepened his confusion [חומש קה״ת].

A third approach offers a psychological and emotional motive for the surprising question. According to this line of thought, Jacob knew exactly who was standing in front of him. His question was a deliberate spiritual and educational tool designed to prompt Joseph to declare that these were his sons. Jacob knew that hearing this statement from his beloved son would awaken a powerful wave of fatherly love and mercy within him. This deep emotional awakening of love and affection was a necessary condition to draw down the Holy Spirit, allowing him to grant the young men a complete and powerful blessing born from a deep inner will [אור החיים, העמק דבר].
