שמות, פרק כ״ח, פסוק מ״ב

The priestly garments are a display of unmatched splendor, designed to bring honor and glory to those who serve God. Yet, the final piece of clothing required for the priests serves a far more basic, human purpose. Unlike the majestic robes and crowns, the linen pants are designed simply for modesty and covering the body [חזקוני, שטיינזלץ, גור אריה, רש״ר הירש]. This strict demand for modesty stands in stark contrast to the idol worship of the ancient world, where religious rituals sometimes involved standing completely naked [קאסוטו]. On a deeper level, these garments cover the physical, instinctual parts of the human body, wrapping them in purity. Because of this, wearing them acts as an atonement for sins related to sexual immorality [קיצור בעל הטורים, רש״ר הירש]. The instruction to make these pants applies equally to Aaron and his sons. While the rest of the priestly wardrobe highlights the difference in status and grandeur between the High Priest and a regular priest, the fundamental obligation of modesty applies equally to everyone, regardless of rank [רש״י, מזרחי, גור אריה].

The pants are made entirely of linen. The specific term used for this fabric implies that the linen threads are woven alone, completely unmixed with any other materials [הכתב והקבלה]. These threads had to be new and folded six times over [תורה תמימה על התורה]. The concept of the fabric being unmixed and "alone" also carries a moral lesson, hinting that a person must remain separate and guarded, keeping far away from forbidden sexual behaviors [אלשיך]. Designed to thoroughly cover the body, the pants resembled the wide riding breeches worn by cavalry. They were tied at the top with special laces and had no openings whatsoever, as any exposure of the body would be a disgrace to the holy garments [תורה תמימה על התורה, ביאור יש״ר, רלב״ג]. They extended from just above the waist down to the knees, ensuring complete coverage of the lower torso [רלב״ג, ביאור יש״ר, שטיינזלץ]. At the same time, they were kept relatively short so that the priests would not trip while performing their duties [אבן עזרא]. The specific focus on these areas of the body serves as a moral guide, reminding people to maintain the highest level of modesty regarding their physical form [אלשיך].

The instruction to make the pants appears at the very end of the clothing preparations, seemingly disconnected from the rest of the wardrobe [ברכת אשר על התורה]. There are two main reasons for this separation. From a practical standpoint, Moses personally dressed the priests in their other garments. However, the priests put the pants on themselves while still outside the sacred area, ensuring they would never enter the Tabernacle unclothed [אור החיים, העמק דבר]. From a legal perspective, because the pants merely prevent disgrace rather than add honor, one might mistakenly think that a priest could perform his duties without them. To prevent this misunderstanding, the instruction is placed at the very end, directly next to a strict warning of punishment. This placement teaches that despite the humble nature of the pants compared to the glorious robes, a priest who serves without them is treated as if he is not a priest at all. His service is entirely invalid, and he faces death at the hands of Heaven [אור החיים, רש״ר הירש, פרדס יוסף].
