Rabbi Moshe Leib Isserles (the Rema) and Rabbi Chaim, the brother of the Maharal of Prague were dear friends all their lives. When Rabbi Isserles assumed the office of Chief Rabbi of the Rabbinical Court of Cracow, Rabbi Chaim accompanied him and served as an adjunct in his rabbinical duties.
After the tragic death of Rabbi Chaim's wife and the year of mourning, it would have been customary to begin the search for a suitable match. When Rabbi Chaim made no attempt to remarry, it was assumed that he was waiting for Rabbi Moshe's intervention, but Rabbi Chaim had his own plan. He contacted a matchmaker and stated his requirements: He wanted a G-d-fearing and modest woman, with the means to support a Torah scholar and a private place where he could study undisturbed. He also required that neither his wife nor her family would reveal Rabbi Chaim's true identity.
Not long after, the matchmaker came up with the perfect match. The good woman was the daughter of a baker, and both she and her father agreed to all of Rabbi Chaim's conditions. A special room was filled with many holy books, and the couple was betrothed in utter secrecy.
A few weeks later, Rabbi Chaim came to his friend and said, "I want you to know that I have decided to travel to my home town to visit my elder brother."
Rabbi Moshe was shocked and deeply saddened by the news. He tried to dissuade Rabbi Chaim, but he refused to discuss his decision. When Rabbi Moshe saw that his words had no effect, he said, "If there is nothing I can do to change your mind, I will at least send you off with great honor."
