Q. Why, what and when is this year the Yom Hameyuchas?
A. Yom Hameyuchas is the Second Day of Sivan, the day before the beginning of the Shloshet Yemei Hagbalah, the Three Days of Restraint that Moshe commanded the Jewish People to observe.
Restraint in approach to Mt. Sinai and restraint from marital intimacy. It is also the forty-sixth day of the Omer, the Sefirah-Count. This year it is the Shabbos Parshas Bamidbor.
On the First of Sivan, Hashem told Moishe Rabbenu to tell our people, “You shall be a Kingdom of Priests and a Holy Nation” (Shemos 19: 6).
On the Second Day of Sivan, when Moshe delivered this message, the nation responded all together, “Everything that G-d has commanded we will do” (Shemos 19: 8). So that true great Day of Acceptance of the Torah by our People was given the title "Yom Hameyuchas" or “Day of Distinction.”
It is also the day that merits the historical relationship with our forefathers, from the Avos onward, as they accepted and kept our Torah, thus they created the true and greatest “Yichus” and family background we were gifted with and sincerely enjoy.
