The erection of the Tabernacle marks a profound transition for the Israelites, initiating a new era characterized by regular Divine service and the dwelling of God's presence within the camp. This historic milestone was intentionally aligned with the renewal of the year, occurring in the month that symbolizes the Exodus and ultimate redemption. Although the physical construction of the Tabernacle and its vessels was completed months earlier in Kislev, God commanded the Israelites to wait until Nisan to assemble it. This delay ensured the structure would be inaugurated in the exact month of their liberation from Egypt [קאסוטו]. Additionally, postponing a public commandment is considered permissible under such circumstances [פרדס יוסף], and the wait allowed time for the vessels to be properly anointed and sanctified [חתם סופר].
The specific date of this event, the first of Nisan [רלב״ג, שטיינזלץ], represents far more than the astronomical occurrence of a new moon; it serves as a powerful symbol of the spiritual and national renewal of the Israelites. The emphasis that this event took place during the day highlights a conscious, moral, and free choice. By acting in the daylight, the Israelites demonstrated a deliberate commitment that stands in stark contrast to the blind, unguided forces of nature often associated with darkness [רש״ר הירש].
Regarding the exact chronology of the inauguration, the primary approach among commentators is that the first of Nisan was the eighth and final day of the dedication period, meaning the seven days of preparation began a week earlier [רמב״ן, אור החיים, העמק דבר, טור הארוך, מלבי״ם, ביאור יש״ר]. A minority view, however, suggests that this day marked the very first day of the inauguration, with the process concluding on the eighth of Nisan [אבן עזרא]. Regardless of the timeline, the command to erect the Tabernacle on this day carried a new sense of permanence. During the preparatory days, Moses repeatedly assembled and dismantled the structure—sometimes several times a day—to train the Levites in their duties and manage the sacrifices. Now, the instruction was to set it up permanently, remaining standing until the Levites would eventually dismantle it for travel during their desert journeys [רמב״ן, טור הארוך, רבנו בחיי, מלבי״ם, ביאור יש״ר, צאינה וראינה]. Because Moses had already been shown the prophetic blueprint of the Tabernacle at Mount Sinai, detailed instructions for assembling the boards and curtains were no longer necessary [רמב״ן, טור הארוך].
The actual assembly of the Tabernacle was accompanied by an open miracle. The wooden boards were impossibly heavy, and all the skilled artisans had failed in their attempts to lift them. God instructed Moses to undertake the task despite the overwhelming physical difficulty. As Moses initiated the effort, the structure miraculously stood upright on its own. This demonstrated to the people that only through Moses could the Tabernacle be established, while also offering a profound lesson on all human endeavor: a person must take the first step, but it is God who ultimately brings the work to completion [כלי יקר, רבנו בחיי, צאינה וראינה, חומש קה״ת]. In this sense, Moses erecting the Tabernacle closely parallels the creation of the world [כלי יקר, אבן עזרא הקצר]. Furthermore, the varied linguistic phrasing used to describe the building process hints at the destiny of the three Temples. Active phrasing reflects the first two Temples, which relied entirely on human action and merit, whereas passive phrasing alludes to the third Temple, which will be established independently of human effort [כלי יקר].
With the structure fully standing, it underwent a profound transformation. Only on this day, after all preparations were complete, did heavenly fire descend as God's glory and cloud enveloped the tent. Up until that moment, it was merely a physical building. From that day forward, it became the true Tent of Meeting—the sacred space where the Divine Presence rested and communed with Moses and the Israelites [העמק דבר, צאינה וראינה].
