Parshas Balak: Rav Ezriel Hildesheimer - Some Shuls Are Easy To Clean
Rav Ezriel Hildesheimer, a talmid of the Aruch L"Ner and together with Rav Shamshon Refoel Hirsch, was a fierce and fearless opponent of the Reform movement. He was once asked, sarcastically, by the members of the Reform Synagogue why the Reform Shuls are always spotless and immaculately kept while the orthodox Shuls are often dirty and not in the best condition. He replied that the orthodox people use their Shul seven days a week and that's how it looks. The reform at best use it for Shabbos and Yom Tov and that's how it looks.
Mah Tovu Ohalecha Yaakov. Not "how beautiful" but "how good" are the Shuls of Am Yisroel!
