The moment of reunion between the brothers and the powerful Egyptian ruler is a dramatic peak of submission, bringing long-held visions into reality. Although the brothers are already waiting inside the ruler's large estate [יריעות שלמה, ברכת אשר על התורה], they now transition deeper into his private space. They are moved from an outer waiting hall directly into the special inner parlor where Joseph is seated [רש״י, מזרחי, אור החיים, רד״ק, העמק דבר, רש״ר הירש, ביאור יש״ר].
They bring their gift forward with a deliberate sense of strength and effort [העמק דבר]. Rather than relying on a single representative to offer the gift, every brother makes sure to present it personally. By holding the gift in their own hands, they demonstrate deep respect, affection, and an eager desire to find favor with the ruler [העמק דבר].
As they fall to the ground, Joseph's childhood dreams finally come to life. The primary approach among commentators is that this moment specifically fulfills his first dream of the wheat sheaves. Just as the sheaves in the dream surrounded Joseph's sheaf and bowed, the brothers, who have journeyed to seek grain, now surround the provider of food and bow to him [העמק דבר, ביאור שטיינזלץ]. This realization is particularly powerful because Benjamin is now present, completing the exact count of eleven brothers [ביאור יש״ר]. Alternatively, this deep bow is seen by some as the fulfillment of the second dream, where eleven stars bow down to Joseph [צרור המור].
