Because at Passover, when we have to eat unleavened bread, the rabbis say, what is the difference between dough that is made into bread, and dough that is made into unleavened bread, or "matzah"?
چون، در عید فطیر، که ما باید نانِ ورنیامده بخوریم، خاخامها میپرسند که تفاوتِ بینِ خمیرِ نانِ معمولی و خمیرِ نانِ ورنیامده (matzah) چسیت؟
