Two bundles of hadassim
Shabbos & Yom Tov
When Rashbi and his son left the cave for the last time, they saw an elderly Jew rushing before Shabbos with two bunches of myrtle. Asked why one would not suffice, he answered: one for "Zachor" and one for "Shamor." Rebbi Shimon told his son, "See how precious the mitzvos are to Yisroel," and their anger at the world melted away. Even a giant who lived thirteen years in pure Torah learned to see the greatness hidden in a simple Jew's love for a mitzvah.
