Whether you are relatively new to the idea of ‘keeping kosher’ or already quite knowledgeable of the issues, this book is for you. I recommend this book as a beginning place for understanding how rooted in Scripture kashrut is, and its importance for those at the beginning of their journeys.
A rabbi was walking down the street when he saw Benny, a member of his synagogue, entering a non-kosher restaurant. Puzzled, he went closer to the restaurant and peeked in the window. "Perhaps he's just going in to ask for directions or use the toilet," the rabbi thought. But sure enough, he watched as Benny was escorted to a table. 
A rabbi was teaching his class about the days following the arrival of the Messiah. "At that time, the Messiah will slaughter the Shor Ha-Bor, the giant ox. The meat from this enormous beast will be enough to feed the entire world!" he said.
