שמות, פרק ל״ו, פסוק ל״א

The stability of the Tabernacle relied heavily on exact connections between its various parts. To ensure the structure stood firm, bars made of acacia wood served as vital reinforcements. Their main purpose was to bind the standing boards together, fully stabilizing the entire building. These reinforcing bars were installed along every single side of the Tabernacle to provide continuous and secure support [ביאור שטיינזלץ].
