דברים, פרק ט״ז, פסוק א׳

The Jewish festivals serve as far more than historical milestones; they are a living expression of the profound connection between nature, human history, and Divine providence. As the Israelites prepare to enter their homeland, the focus shifts away from observances practiced in the desert, such as the Sabbath, the New Year, and the Day of Atonement. Instead, the emphasis is placed entirely on the three pilgrimage festivals. These celebrations only achieve their complete meaning within the rhythm of agricultural life in the land, requiring the people to journey together to the central location chosen by God [רמב״ן, רש״ר הירש, ברכת אשר].

The primary approach among commentators is that the instruction to guard the month of spring is not merely a call to remember the holiday, but a practical, legal requirement to adjust the calendar. The Hebrew calendar relies on the lunar cycle, which is roughly eleven days shorter than the solar year. Without human intervention, the festival of Passover would continuously drift backward through the seasons. Therefore, the rabbinic court is required to calculate the dates and, when necessary, add an intercalary month to guarantee that the holiday always falls during the spring. The term for spring here does not refer to a specific month's name—as the modern names of the Hebrew months actually originate from Babylon—but rather describes the season when the weather is mild and the grain, particularly the barley, begins to ripen [אבן עזרא, תורה תמימה, ביאור יש״ר, בכור שור].

Beyond its practical application, this alignment carries a deep philosophical message. The rebirth of nature is deliberately intertwined with the rebirth of the nation. The same God who awakens the natural world from its winter slumber is the one who delivered the Israelites from slavery into freedom. This connection actively rejects the ancient worship of nature, demonstrating instead that the Creator governs both the predictable laws of the physical world and the unfolding events of human history [רש״ר הירש]. Furthermore, the commandment to adjust the calendar grants humanity an extraordinary spiritual power to intervene in the flow of time, allowing people to correct the past and complete what is missing [חומש קה״ת]. On a symbolic level, the spring season reflects the experience of the nation in exile. Just as a seed must decay in the earth before it can sprout with fresh life, the Israelites may sometimes appear powerless in the world, yet they are destined to renew their strength and experience redemption [העמק דבר].

Regarding the preparation of the Passover sacrifice, a clear distinction is made between the original event in Egypt and the permanent practice in the land. While the first Passover was eaten in the privacy of individual homes, the permanent commandment demands that the people gather to sacrifice and celebrate together at God's chosen center [אברבנאל]. The specific language used to describe the preparation of the offering teaches a crucial legal principle. Every step of the process must be performed with pure, deliberate intention specifically for the Passover sacrifice; if the actions are dedicated to any other type of offering, the sacrifice becomes invalid [תורה תמימה, שפתי כהן, רש״ר הירש].

The historical account concludes by noting that God brought the Israelites out of Egypt at night. This presents a historical difficulty, as other accounts state explicitly that the physical departure occurred in the middle of the day. The commentators agree that while the actual journey began in daylight, the essential, legal redemption was achieved during the night. It was in the darkness that the Egyptian firstborns were struck, the power of the empire was broken, and Pharaoh finally summoned the leaders to grant them official permission to leave [רש״י, רבנו בחיי, רלב״ג, מלבי״ם]. The night also represents the dominance of harsh external forces and strict justice, which God actively subdued at that very moment [רקנאטי, אלשיך]. Conceptually, the nighttime redemption highlights the complete passivity of the Israelites in their own liberation. Much like an infant born into life from the darkness of the womb without any effort of its own, the nation was born into freedom from the darkness of Egypt entirely through the power of God [רש״ר הירש].
