שמות, פרק ל״ח, פסוק ה׳

Preparing the structure for travel required special hardware to hold the carrying poles securely. To achieve this, four rings were cast and attached directly to the four corners of the copper grate. These rings functioned as housings, acting as specific receptacles for the poles. By providing a secure place to insert the poles, this practical design ensured that the entire structure could be lifted and transported safely [ביאור שטיינזלץ].
