When one fulfills the mitzvah of Kimcha D’Pischa, he also fulfills the mitzvah of V’Ahavta L’Reacha Komocha. Sefer Divrei Chana (Chelek 2, page 125) relates that when the Kaloshitzer Rebbe zy”a lived in the city of Kashau, there was a resident of the city who was known as “Red Berish”. This man was very poor, and he was a very coarse and vulgar person.
On Chol Hamoed Pesach, as the Rebbe was entering the bais medrash to daven and was emotionally declaring, “Behold, I accept upon myself the mitzvah to love every Jew like myself”, Red Berish ran over to him and audaciously said, “You claim to love every Jew? The Rebbe has all that he needs for yomtov in his house but my house is empty. My family has no matzoh, meat, eggs or even apples!”
The Rebbe remained silent and did not reply. Instead, he immediately put on his talis and davened quickly, which was very unusual for him.
After davening, he ran home. A few minutes later, he was seen running through the streets with two large bags full of food. He ran for a long time until he came to Red Berish’s house on the outskirts of town, and he handed over the food with a smile. Berish then said that he sees that the Rebbe really does love every Jew like himself.
