וכי־ימוך אחיך ומטה ידו עמך והחזקת בו (בהר כה:לה)

The story is told about the holy Rabbi Dovid, author of the Turei Zohov (known by its acronym “Taz”), who was approached by someone who wanted to borrow one złoty.   When the Taz realized he didn’t possess a złoty, he handed his silver goblet to the petitioner, telling him to take it to the pawnbroker and borrow one złoty against his Kiddush Becher.  The Rav reckoned that he could redeem his precious Kiddush cup by the end of the week when his wages are delivered.  When the wages arrived, and he sent for the Becher, the Taz was informed that – instead of one złoty, the poor man borrowed two złotys!

Instead of becoming angry at this person’s rudeness, the Taz was happy and said: “Had I lent him one złoty, this poor man would have still been missing one more złoty, but by lending him my Kiddush cup, this poor borrower received his needs in full, without undue embarrassment!
