The completion of the Tabernacle marked a monumental turning point in history, as the Divine Presence finally descended to rest within the Israelite camp. Occurring on the first day of the month of Nissan in the second year following the exodus from Egypt, this event is strategically recorded immediately following the Priestly Blessing. The primary approach among commentators is that this proximity teaches a profound truth: the Divine Presence only dwells in a place of peace. With the Tabernacle standing, the lingering tension between God and the Israelites from the sin of the Golden Calf dissolved entirely, and harmful spiritual forces that had previously roamed the world were permanently banished [רבנו בחיי, מגלה עמוקות].
Rather than simply noting the day the structure was put up, the narrative emphasizes the final completion of the process. The primary approach among commentators is that during the preceding seven days of inauguration, Moses would erect and dismantle the Tabernacle each morning and evening to practice the holy service. Only on the eighth day did he set it up permanently. Therefore, this day marked the absolute conclusion of these daily erections [רש״י, רמב״ן, תורה תמימה].
Beyond the practical completion, there is a deep symbolic resonance. The term used to describe this completion is written in a way that can also be read as "bride." This alludes to the idea that on this day, the Israelites were like a bride entering the wedding canopy with their Creator, with the Tabernacle acting as the canopy that united God and His people [רש״י, אור החיים, גור אריה]. Yet, the opening language of the narrative also carries an undertone of sorrow. This sadness stemmed either from the tragic death of Aaron's sons, Nadav and Avihu, which occurred on that very day, or from Moses' own personal sorrow that his daily task of assembling and disassembling the structure—a duty that brought him immense spiritual joy—had finally come to an end [שפתי כהן].
Although the artisans actually crafted the boards and vessels, the physical erection of the sanctuary is attributed entirely to Moses. This credit reflects his total devotion. Moses dedicated his soul to the project, ensuring every detail perfectly mirrored the spiritual blueprint God had shown him on the mountain, and he actively battled spiritual forces that sought to hinder its construction [רש״י, רבנו בחיי, מגלה עמוקות]. Furthermore, his actions on earth had cosmic parallels; by erecting the physical Tabernacle below, Moses simultaneously established a heavenly, spiritual Tabernacle above, serving as the conduit through which the prayers of Israel and the souls of the righteous ascend [רבנו בחיי, אלשיך].
The narrative deliberately repeats the actions of anointing and sanctifying the sanctuary, the altar, and all their respective vessels. This repetition establishes a fundamental principle regarding the sanctuary's holiness: no single vessel became holy in isolation. Sanctification only took effect once everything was anointed together. The Tabernacle was not a random assortment of sacred objects, but a complete, organic system where every detail relied on the integrity of the whole. The sanctuary and its vessels represented the ultimate spiritual destination, while the altar and its tools represented the means to reach it. True holiness was achieved only when all components were united toward a single purpose [רש״ר הירש, ספרי, שפתי כהן].
This sanctification was carried out using special anointing oil, though there is an additional view that the altar was also sanctified with sprinkled blood [רמב״ן, אבן עזרא]. This physical anointing was a unique, one-time requirement specific to the generation in the wilderness, designed to consecrate the original vessels for all time. In future generations, the vessels of the Temple would no longer require anointing oil; instead, they would become instantly sanctified simply through their active use in the holy service [תורה תמימה, חזקוני].
