The final moments between a father and his family encompass requests concerning the body, the soul, and the legacy of future generations. Jacob's instructions to Joseph are not merely technical funeral arrangements but a spiritual testament reflecting a deep bond with the Land of Israel, the nation's ancestors, and God's providence. The primary approach among commentators is that the initial mention of resting with his ancestors refers to the exact moment of passing and the departure of the soul, as chronologically, death precedes the physical carrying and burial of the body [רש״י, אבן עזרא, מזרחי, ריב״א, שפתי חכמים, ביאור יש״ר, הדר זקנים, רש ר הירש]. Alternatively, this portrays the physical placement of the deceased's bed in the center of the room so mourners can gather around it [ספורנו, מחוקקי יהודה]. A more profound layer distinguishes between body and soul. While subsequent instructions address physical care, the concept of resting with the ancestors describes the soul immediately ascending to join the righteous [רבנו בחיי, מלבי״ם, צרור המור]. Furthermore, the imagery of lying down suggests that death is a temporary state of sleep from which a person will eventually awaken, alluding to the future resurrection [אם למקרא, חנוכת התורה].
Jacob expresses fierce opposition to being buried in Egypt, even temporarily. According to Jewish law, relocating a deceased person requires taking along some of the soil from the original grave, and Jacob abhorred the thought of impure Egyptian earth being transferred and buried with him in the Land of Israel [העמק דבר, פני דוד, חזקוני, חתם סופר, תורה תמימה]. He also feared the Egyptians might turn his resting place into a site of idol worship, and he wished to avoid the painful underground journey of the body returning to the Land of Israel at the time of resurrection [תורה תמימה]. Additionally, he wanted to ensure his descendants would never have to leave the Land of Israel and travel to an impure land simply to visit his grave [קונטרס חיבה יתירה]. On a practical level, Jacob advises Joseph to wait until the formal mourning period concludes before moving him, ensuring the Egyptians would not oppose his departure [ספורנו].
The insistence on being buried in the ancestral plot ensures the righteous patriarch rests beside his righteous forebears in the Cave of Machpelah [רבנו בחיי, מחוקקי יהודה]. This specific location is crucial because it was legally purchased and stands as the private property of the patriarchs, serving as a vital physical anchor in the land before the time for national conquest had arrived [ביאור יש״ר, ברכת אשר]. There is also a mystical dimension to this request, as true spiritual perfection is achieved only when the physical body is interred in the holy soil of the Land of Israel [רקנאטי].
Joseph's immediate agreement embodies deep respect and a willing acceptance of this responsibility. He declares his readiness to fulfill the duty completely out of his own free will and his obligation to honor his father. Because of this eager commitment, a formal oath is unnecessary, as an oath might imply he is acting out of compulsion [אור החיים, מלבי״ם, צרור המור, רבינו חננאל]. Out of respect for either his own high position or his father's dignity, Joseph refrains from performing the physical gesture of taking an oath, asserting that his spoken word and personal guarantee are entirely sufficient [העמק דבר, פני דוד]. He assures his father that he will not merely rely on God's promise to bring Jacob out of Egypt, but will take active, practical steps to make it happen [הטור הארוך, צרור המור]. Ultimately, Joseph's pledge carries a vision for the future. Just as his father commands him now, Joseph promises that when his own time comes, he too will instruct his brothers and the tribes to carry his bones out of Egypt [רבנו בחיי, הטור הארוך, צאינה וראינה, הדר זקנים, דעת זקנים].
