Facing the prospect of a long journey to Egypt, an aging father needed both comfort and reassurance. Joseph seeks to calm his father's fears and encourage him to travel by presenting a complete picture of his current status and capabilities. The primary approach among commentators is that detailing this honor and greatness is meant to erase any anxiety Jacob might have about relocating. Knowing his son possesses the power and resources to provide for him offers a deep sense of security [רשב״ם, חזקוני]. Beyond practical safety, this news is intended to bring joy to Jacob's heart [ספורנו]. The extensive detail provided about Joseph's success is precisely what will motivate Jacob to hurry and make the journey [העמק דבר].
When Joseph instructs his brothers to tell their father about his glory [ביאור שטיינזלץ], he is not merely referring to his technical authority as a ruler [ביאור שטיינזלץ]. Instead, he speaks of a position filled with genuine respect and love. While ordinary rulers often face hidden hatred from their subjects and receive only empty flattery, Joseph highlights that he has earned the sincere, heartfelt honor of the Egyptian people [מלבי״ם]. The fact that Joseph can speak of his own glory without fear of arrogance reveals his high spiritual standing. He has reached a state where greatness does not corrupt him, allowing him to accept respect without falling into pride [פרדס יוסף]. Furthermore, this honor is deeply connected to his ability to withstand past trials. Joseph subtly hints to his brothers that his high rank is a direct result of maintaining his righteousness and remaining pure from sin [חנוכת התורה].
To ensure that Jacob fully accepts this incredible news, Joseph emphasizes that his brothers must share exactly what they have seen. They are not merely passing along secondhand rumors; they are eyewitnesses who have experienced his greatness firsthand, which will convince Jacob to believe them [ביאור יש״ר]. Additionally, as visitors arriving from the outside, the brothers are in a unique position to observe the true respect and public support Joseph enjoys. Such genuine admiration is often hidden from a ruler who is constantly surrounded by flatterers, making the brothers the perfect messengers to verify the reality of Joseph's standing [מלבי״ם].
