שמות, פרק ל״ה, פסוק ט״ז

The construction of the Tabernacle required careful attention to the items placed in its outer courtyard. The inventory of crafted items focuses entirely on these external tools and structures [ביאור שטיינזלץ]. Among the essential pieces were a specialized copper grate, functioning essentially as a metal net, and the heavy base that supported the washbasin [ביאור שטיינזלץ].

Moving these items through the desert presented unique logistical challenges. While major structures like the altar were equipped with designated poles so they could be carried by hand, the washbasin and its base lacked these carrying poles entirely. Because they were not designed to be carried on the shoulders of the workers like the rest of the sacred items, they were instead loaded and transported on wagons during the journeys of the Israelites [אבן עזרא].
