The biblical festivals are not designed for closed, private family celebrations, but rather serve as epicenters of broad communal and spiritual joy. They draw a circle of celebration that connects the individual, the family, the vulnerable members of society, and the Divine Presence. The primary approach among commentators is that the commandment to rejoice refers first and foremost to the physical enjoyment of eating the meat of the peace offerings brought during the holiday [תורה תמימה, רלב״ג, רש ר הירש].
Yet, a striking distinction exists among the pilgrimage festivals: while joy is explicitly commanded on Shavuot and Sukkot, it is noticeably absent regarding Passover. This omission stems from Passover's focus on the miracle of the Exodus, occurring at a time when the grain still stands in the fields, before agricultural gifts can be distributed to the poor. Shavuot, however, marks the wheat harvest, bringing the initial joy of the new crop, while Sukkot represents a complete and doubled joy, as the entire harvest has been gathered into the home and agricultural labor has ceased [בכור שור, קיצור בעל הטורים, הדר זקנים, מלבי״ם].
Beyond the agricultural cycle, the three festivals serve as a comprehensive allegory for the stages of human life [שפתי כהן]. Passover symbolizes the first twenty years, a period characterized by the struggle with physical desires and an incomplete sense of joy. Shavuot represents the middle years, where a person is burdened with providing for a family, allowing only for partial joy. Sukkot reflects old age, a time when physical desires diminish, freeing the individual to experience the complete spiritual joy of connecting to God. This profound, wholehearted joy is ultimately achieved through the study of Torah and the performance of kindness and charity [פני דוד].
The celebration must encompass not only the immediate family, such as sons and daughters, but also the landless Levite who relies on the harvest, along with the convert, the orphan, and the widow [ביאור שטיינזלץ]. Because these vulnerable groups lack economic and familial support, there is a strict requirement to fold them into the family unit, share the pilgrimage and festive meals with them, and provide them with the agricultural gifts that are abundant during the harvest season [ספורנו, רלב״ג, רש ר הירש]. This dynamic creates a fascinating divine equation. God presents a balance between four members of the human household, which includes the son, daughter, bondsman, and bondswoman, and four members of His own vulnerable household, which includes the Levite, the convert, the orphan, and the widow. The promise is clear: if a person takes care to bring joy to God's four people, God will ensure the joy of that person's family in the Chosen House [רש״י, רא״ש].
There is a subtle distinction in how these vulnerable individuals are integrated into the community. The Levite is associated with the city gates, whereas the poor are described as being in one's immediate vicinity. One perspective explains that on Shavuot, a full festival day, charity administrators are forbidden from making public appeals at the city gates, unlike the intermediate days of Sukkot. Therefore, provisions for the poor are gathered discreetly within the local neighborhood, whereas the Levite receives his tithes with dignity, independent of any charity collection [העמק דבר]. Another approach links this distinction to the laws of cooking on a festival. The concept of those at the gates typically denotes a resident alien, for whom one is not permitted to cook on a festival day, and who is not allowed to reside in Jerusalem. Consequently, on Shavuot, the focus shifts to the convert in the immediate vicinity, referring specifically to a righteous convert who can fully and legally participate in the festival joy and meals [צפנת פענח].
Finally, all of this celebration is bound to the specific location that God chooses to establish His name. This emphasizes that once the Temple was built, the festival offerings had to be brought exclusively to Jerusalem. The formal legal obligation to make the pilgrimage only took effect once God had selected the exact site for His Divine Presence to rest [רמב״ן].
