Sivan 2 is marked on the Jewish calendar as Yom HaMeyuchas (“Day of Distinction”); it was on this day that G-d told Moses — when Moses ascended Mount Sinai for the first time — to tell the people of Israel: “You shall be My chosen treasure from among all the nations, for all the earth is Mine. You shall be to Me a kingdom of priests and a holy nation” (Exodus 19:4-6).
