You invest no small sum in them, and you don’t even know them. You send them another gift from time to time, you give extra on Erev Chag and other special occasions. But the chances that you will actually meet them is close to zero.
The Gedolei Hador probably don’t know you personally. Maybe you went to them, and received a berachah or an eitzah, but hundreds of new people come every day, and the Gedolim probably don’t remember your name or how you look.
At Matan Torah, the 600,000 adult men probably did not know each other personally, yet they still encamped as one person with one heart. They felt Jewish responsibility for one another, there was a strong personal commitment of each member of the Jewish people to his brother.
Jewish responsibility is in the genes of Am Yisrael; it is passed down eternally, powerfully and undefeatably. Jew to Jew is like brother to brother, like parent to child: we give to the poor without knowing them personally, only because they are our Jewish brethren. The Gedolei Hador travel to Teveria to daven for us, only because of their love for Hashem’s children.
They daven for our children as if they were their own children. They care whether your son will see success in his Torah learning, will love the mitzvos and give you nachas. They care about you, and we care about the children of Vaad Harabbanim.
One person, with one heart.
It doesn’t happen on any other day, and not for any other purpose. The one and only time that the Gedolei Hador gather at the tomb of the Shelah Hakadosh, on the same day and at the same time, which takes a complex logistical effort, is for Vaad Harabbanim’s Maamad Tefilah of Erev Rosh Chodesh Sivan.
The Gedolei Hador leave everything behind, close the beloved Gemara, leave their talmidim waiting, put sheilos in Halachah on the side, and travel to Teveria. chassidish Rebbes close the always-crowded waiting room and make the journey, with to the tomb of the Shelah Hakadosh.
They travel and take your own little Moishie along in their hearts, to daven for him that he should grow in Torah. The burden of the Tzibbur rests on their shoulders, fateful matters come to their doorstep, but now they are only with your child.
If we care about our children, if we want them to be good, proper Jews, doers of Hashem’s will and learners of His Torah, we will make sure they will be there, at any cost.
Your tzedakah at this time to Vaad Harabbanim is what does it.
