The preparations for the journey back to Canaan mark a shift from promises to concrete actions, as the brothers gather the transport and supplies needed to bring their father and his household to Egypt. Following their instructions, they begin readying themselves for the trip home [ביאור שטיינזלץ]. They load their animals with grain that is provided to them entirely free of charge [ביאור יש״ר]. However, the load they pack is relatively light, consisting mostly of animal feed for the road, as they anticipate turning around and coming right back [מלבי״ם]. At this early stage, their intention is not to settle in Egypt permanently [העמק דבר].
The provision of wagons by royal decree is a matter of significant legal and political importance. Exporting such vehicles, along with the pure animals that pull them, is strictly prohibited in Egypt and requires explicit permission from the king [רד״ק, מלבי״ם, צפנת פענח]. Practically, these wagons allow the brothers to carry a vastly larger amount of food and equipment [ביאור שטיינזלץ]. Yet, a deeper family and political dynamic surrounds their use. During the famine, the king has banned the export of grain, mandating that anyone in need of food must travel directly to Egypt. Joseph, fearing his father might resist leaving Canaan, emphasizes the king's command as a decisive argument to force the move. The brothers initially hide from their father that they are essentially compelled to relocate. It is only after God appears to Jacob and explicitly permits him to descend to Egypt that they finally reveal the wagons were sent by royal decree [העמק דבר]. Adding to this complexity, one tradition suggests that Judah actually burns the original wagons sent by the king, forcing Joseph to supply replacements [שפתי כהן].
Beyond their practical utility, the wagons carry a profoundly personal, hidden message designed to prove to Jacob that his son is truly alive. The vehicles serve as a subtle reminder of a calf, referencing the very last Jewish legal topic Joseph and his father studied together before their painful separation. This specific law deals with the strict obligation to escort guests and provide them with food to protect them from the dangers of the road. By sending these supplied vehicles, Joseph demonstrates to his father that he has not forgotten their shared studies [רבנו בחיי, צאינה וראינה]. To complete the preparations, Joseph ensures that alongside the abundant grain meant for the family's long-term survival, they are also equipped with dedicated food rations intended strictly for the journey itself [ביאור יש״ר].
