ויקרא, פרק כ״ג, פסוק מ״א

The festival of Sukkot is established not merely as an agricultural milestone marking the end of the harvest, but as an event of profound, eternal spiritual significance. By fixing its timing absolutely within the calendar, the celebration is detached from fluctuating earthly circumstances, transforming it into a constant expression of the bond between the Israelites and God. The mandate to celebrate entails practical expressions of profound joy, encompassing dancing and rejoicing that reflect an immense love and admiration for God [תורה תמימה]. Concurrently, it establishes the obligation to bring peace offerings and burnt offerings on the festival, performed with pure devotion to His name [תורה תמימה].

The primary approach among commentators is that while the celebration spans a full week, the main obligation to bring the festival offering is concentrated solely on the first day. The remaining time serves as a grace period, allowing anyone who missed the initial opportunity to fulfill their duty later in the week. The specific timeframe of seven available days also accounts for the Sabbath; since the extended festival period always includes one Sabbath when offerings are not brought, exactly seven days remain available for this purpose [תורה תמימה, מלבי״ם]. This compensation period is strictly limited to the current year, meaning a missed offering cannot be made up during the festival of the following year [רלב״ג]. Furthermore, this highlights a unique aspect of the holiday, as it is the only time of the year requiring a continuous seven-day presence at the Temple, distinguishing it from Passover [רד צ הופמן].

Because it is deeply associated with the ingathering of crops, one might mistakenly assume the festival depends on agricultural success, or that it only applies within the Land of Israel while the Temple stands. To counter this, it is defined as an eternal duty, binding even in exile, even for those without fields or vineyards, and even in regions where the harvest occurs in a different season [ביאור יש״ר]. Despite the sorrow of exile and the absence of the Temple, the joy of the festival is preserved through a sense of spiritual triumph following the solemn days of judgment, with the taking of the four species serving as a symbol of victory. This joy is further enriched by the Divine Presence of the Patriarchs visiting the temporary dwellings. Sitting in these fragile huts during exile recalls the protective clouds of glory from the Exodus and offers hope, serving as a reminder that the current physical world is merely temporary in the journey toward ultimate redemption [אלשיך].

The exact timing in the seventh month is reiterated to prevent any flexibility. There might be a temptation to delay the festival if the harvest is late in certain regions—a change historically attempted by Jeroboam. Thus, the timing is firmly anchored to the autumn, entirely independent of actual agricultural conditions [העמק דבר, רד צ הופמן]. Placing the festival in this specific month, rather than in the spring when the Exodus actually occurred, serves to prove that moving into the temporary dwellings is done purely to fulfill the Commandment. In the spring, as the weather warms, it is natural to seek shade outdoors. However, in the autumn, as the rainy season begins and people naturally retreat to the comfort of their homes, stepping outside into a fragile hut clearly demonstrates that the Israelites are acting strictly upon God's command [אלשיך].

Ultimately, the specific instruction regarding the celebration's boundaries indicates that the grace period for bringing offerings extends into the subsequent holiday of the eighth day, which is considered part of the autumn celebrations [תורה תמימה, מלבי״ם]. At the same time, this precise framing ensures that the celebration is strictly confined to the days of the festival itself, rather than extending to the rest of the month [מלבי״ם, אדרת אליהו].
