שמות, פרק כ״ו, פסוק ב׳

The construction of the Tabernacle required perfect precision, where every physical detail carried profound practical and conceptual meaning. The inner layer of curtains, where the presence of God rested, was carefully measured to fit the structure perfectly. The standard unit of measurement was the cubit, representing the distance from an adult's elbow to their fingertips [ביאור שטיינזלץ]. When these massive curtains, spanning twenty-eight cubits, were draped across the width of the Tabernacle, they fit with mathematical exactness. Ten cubits formed the flat roof over the interior space, leaving nine cubits to hang down the northern side and nine down the southern side. Since the wooden walls stood exactly ten cubits high, the draped curtains covered almost the entire wall, leaving only the bottommost cubit exposed. This single visible row at the bottom consisted of the hollow silver sockets that served as the foundation for the walls [מזרחי, תורה תמימה].

The measuring unit used for these specific curtains was actually larger than the standard cubit used for the rest of the Tabernacle vessels [העמק דבר, רש ר הירש]. Because this measurement was non-standard, there was a real risk of error if multiple weavers worked at the same time. To ensure that every curtain matched perfectly, the artisans were instructed to weave one complete curtain first. This initial piece then served as the exact master template for all the others [העמק דבר]. Furthermore, each curtain had to be woven as a single, continuous piece. If a thread snapped during the process, the weavers had to tie the ends together to preserve the fabric's integrity. This necessary act of tying threads in the Tabernacle serves as the source from which the sages derived the prohibition against tying knots on the Sabbath [תורה תמימה].

Beyond the practical architecture, the inner space of the Tabernacle was designed to mirror the universe itself. The concept of these coverings echoes the imagery of God stretching out the heavens like a curtain. When a person stood inside the sanctuary and looked up, the massive tapestries joined together by hooks looked exactly like a vast sky filled with stars [אבן עזרא, רבנו בחיי, מלבי״ם]. The sheer scale of producing a single continuous fabric of such enormous size was a marvel, with some viewing its successful creation as an actual miracle [רבנו בחיי].
