שמות, פרק ל״ט, פסוק כ״ט

The priestly garments were primarily characterized by a pure white appearance. However, one specific item broke this uniformity and added vibrant shades to the priests' attire. This item was the sash, a belt worn over the garments. Early commentators debate whether this colorful sash belonged exclusively to the High Priest or if it was worn by regular priests as well [רשב״ם, העמק דבר]. The primary approach among commentators is that the instruction applies to all priests. Therefore, while the linen tunics and hats of the regular priests were completely white, the sash they tied around themselves was made from a mixture of linen and dyed wool in shades of blue, purple, and crimson. This addition provided color and life to their otherwise plain appearance [ביאור שטיינזלץ, העמק דבר].

While items like tunics and hats are grouped together as plural objects, the sash stands alone as a singular item. This distinction reflects a practical difference in how the garments were worn. Tunics and pants required precise, custom tailoring to fit the exact measurements of each individual priest. Similarly, the hats required a unique style of wrapping for each person. In contrast, the sash was a universal item. A single belt could fit any priest regardless of his size. This singular nature teaches that Aaron's sash was completely identical to and valid for his sons [העמק דבר, פרדס יוסף].

The completion of these garments is accompanied by the note that everything was done exactly as God commanded Moses. The frequent repetition of Moses' name throughout the description of the Tabernacle construction is not accidental. Instead, it serves as a form of divine compensation. Following the sin of the Golden Calf, Moses asked God to erase his name from His book. In response, God promised to record his name abundantly throughout the Torah. This dynamic is compared to a king who commanded his servant to build a palace. The loyal servant made sure to write the king's name on every single item. When the king finally entered the palace, He rewarded the servant by writing the servant's name repeatedly as a mark of honor and respect [פענח רזא].
