A man came to the Brisker Rav, Yitzchak Zev Soleveitchik, before Pesach and asked, “Is it permitted to use milk instead of wine for the Four Cups” that are drunk at the Seider? The rabbi took 5 rubles from his pocket and gave them to the man.
The rabbi’s wife asked “wouldn’t one ruble have been enough for him to buy wine?”
“Perhaps,” responded the rabbi, “but from his question, it was clear that he didn’t have money for meat either, for one can’t eat meat and use milk for the Four Cups. Therefore, I gave him enough money for both meat and wine for his Pesach Seider.”
