R’ Shmuel Levitin headed a Yeshiva in Nevel, Russia for training Rabbis. He remarked, “My Yeshiva produces machine Rabbis,” and explained, “When manufacturing machine tzitizs, one inserts wool on one side of the machine and tzitzis emerge from the other end. With matzos, one inserts flour into one end, and Matzo comes out the other. In my Yeshiva, א גוי אן עם הארץ walks in from one side and an ordained Rabbi walks out the other.
