The Sealed Pouch of Gold
Parnassah
According to tradition, Rav Zerach never accepted gifts or donations in any situation. Towards the end of his life he lost his wealth, and the parnas (president of the congregation) sent him a sum of money, a package filled with gold coins.
Rav Zerach staunchly refused to accept gifts, yet he was in a quandary. How could he refuse the parnas? It would be an insult. So he gratefully accepted the pouch of coins and hid it. In his will, he left instructions that the money be returned to its owner.
After Rav Zerach passed away, the bag was found sealed. It had never been opened.
