'This is a fascinating book about the history of a particular halachic (Jewish legal) concept; namely, the issue of a Jew providing testimony against a fellow Jew in a non-Jewish court. … The book is a masterpiece of legal analysis and a brilliant case study of tracing an interesting and relevant legal concept through nearly two thousand years of legal history. … The writing is clear and lucid, and even though it is structured in a manner similar to a legal treatise, this book can be understood by anyone interested in the subject matter at hand or someone with an even basic familiarity with Jewish law.' David Tesler, Association of Jewish Libraries
