שמות, פרק ל״ו, פסוק ל״ו

Inside the Tabernacle, a dedicated system was built to support the dividing curtain. This structure consisted of wooden pillars completely covered in gold, resting firmly on silver bases. Golden hooks were set directly into four pillars made of acacia wood, acting as the hangers from which the curtain was suspended [ביאור שטיינזלץ].

The specific number of pillars chosen for this task was carefully planned rather than random. Exactly four acacia pillars were dedicated to holding up this inner curtain. This deliberate choice stands in direct contrast to the entrance of the Tabernacle, which was designed with a set of five pillars, pointing to a unique and intentional design for this inner boundary [חזקוני].
