שמות, פרק י״ט, פסוק י״ד

Moments before the historic revelation at Mount Sinai, a vital transition takes place. Moses acts as the essential bridge between the Divine command and the physical and mental preparation of the Israelites. His immediate actions ensure that the nation is entirely ready to receive the Torah, carrying out God's instructions with absolute precision [קאסוטו].

God's command to descend to the people was given to Moses while he was still high upon the mountain [רמב״ן, הטור הארוך]. Without delay, he made his way down to the Israelites, who were standing nearby, eagerly waiting to hear the word of God [העמק דבר]. This descent occurred on the fourth day of the month of Sivan [חזקוני]. Rather than returning to his own tent or tending to his personal affairs, Moses went directly to the public [רש״י, רמב״ן]. In this context, his personal affairs were not mundane tasks, but rather his own profound spiritual elevation on the mountain. By leaving these lofty spiritual heights to address the basic needs of the nation, Moses established an enduring model of leadership. He demonstrated that an individual, and certainly a public leader, must prioritize the well-being and needs of others over their own spiritual perfection [פרדס יוסף, חומש קה״ת].

Upon reaching the people, Moses conveyed God's exact instructions, prompting the Israelites to immediately separate from marital relations [העמק דבר]. However, this sanctification was not merely a transmission of rules; it was an active, intense effort by Moses to elevate the nation until they willingly embraced the holiness of the Torah and its Commandments [הכתב והקבלה]. It is significant that Moses actively sanctified the people, rather than the people simply sanctifying themselves. Through his passionate and inspiring words, Moses penetrated their hearts. He purified them not only through external acts of separation but deeply within their innermost thoughts and reflections [העמק דבר].

Following this spiritual awakening, the people immediately set about cleaning their garments [העמק דבר]. Typically, a process of purification involves washing that is completed by the evening of the same day. In this unique instance, however, the Israelites were granted an extended preparation period of three days. This longer timeframe was necessary due to the presence of the mixed multitude among the nation, which required a more gradual and thorough period of readiness before the monumental event [חזקוני].
