בעבור תברכך נפשי (תולדות כז:ד)

Reb Yitzchok Shlomo Ungar, the Rav of Chug Chasam Sofer in Bnei Brak zt”l related:

Maran Reb Aharon of Belz zt”l once visited the Pressburger Rav zt”l in Yerushalayim. Before Maran Reb Aharon departed, he asked the Pressburger Rav to bentch (bless) him.

This request shook the Pressburger Rav and could not proceed to bentch Maran Reb Aharon.  Reb Aharon insisted, and the Pressburger Rav started verbalizing some brachos. Maran Reb Aharon said: “I did not mean this.”  He took the hands of the Pressburger Rav in his hands and placed them on his head, asking the Pressburger Rav to bless him with the bracha of “יברכך” (the blessing of the Kohanim).

The Pressburger Rav started crying and proceeded to bentch Maran and then bid him farewell.

Sometime later, Reb Yitzchok Shloime escorted the Pressburger Rav to the Yeshivas Chayei Olam in Yerushalayim.  A group of homeless people sat nearby begging for tzedakah – charity.  The Pressburger Rav approached one of the beggars and handed him a coin.  The beggar thanked him profusely, and to everyone’s amazement, the Pressburger Rav asked the beggar to bentch him.  The beggar started mumbling,, but the Pressburger Rav said: “This is not what I meant. Place your hands on my head and bentch me with the blessing of the Kohanim”.  The beggar proceeded to do so and bentched the Rav.

The Pressburger Rav told Reb Yitzchok Shloime: “If I am worthy to bentch the Belzer Rav, then the beggar can bentch me”!
