DH and I were in a marvelous European city , in a Jewish museum attached to one of the most remarkable synagogues in the world , and the tour guide was showing us different artifacts . When we got to the ketubah section , the guide told us about the nature of the Jewish marriage contract . It was all information that we ' ve heard dozens , maybe hundreds , of times .
