Make for yourself a heart of many rooms, and enter into it the words of Beit Shammai and the words of Beit Hillel, the words of those who declare a matter impure, and those who declare it pure.
אע"פ שנחלקו ב"ש וב"ה ... ללמדך שחיבה וריעות נוהגים זה בזה, לקיים מה שנאמר (זכריה ח, יט) האמת והשלום אהבו.
Although Beit Shammai and Beit Hillel disagreed (on many critical issues) ... nevertheless .. they behaved with love and friendship toward one another, as it says in Zecharia, "TRUTH and PEACE they loved."
