Three banknotes with a face value of 100 Israeli lirahs each, given by the Steipler to his disciple and associate Rabbi Avraham Hurwitz, author of Orchot Rabbeinu. There is a small note attached to the banknotes (written on the reverse side of a salvation-kvittel which had been given to the Steipler), written in the Steipler's handwriting: "And these three hundreds are for an etrog, as it is customary to be blessed to be inscribed and sealed for good in all matters." Rabbi Hurwitz, with his well-known devotion to the Steipler, preferred to keep this money for segulah and blessing, and he bought the etrog with other money. The money and the note are placed in an envelope on which the Steipler wrote: "To Rabbi A. Hurwitz."
Items which belonged to tzaddikim are known to be segulahs for blessing and salvation, as is well-known and is brought in many ancient books. Even banknotes from the hands of tzaddikim were used as real amulets.
