Like most of the rabbis of the time, Rashi accepted no compensation from the community for his services, and he probably lived from what he earned by viticulture. Once he begs a correspondent to excuse the shortness of his letter, because he and his family were busy with the vintage. "All the Jews," he said, "are at this moment engaged in the vineyards." In a letter to his son-in-law Meir, he gives a description of the wine- presses of Troyes, in the installation of which a change had been made. It was deemed fitting that the scholar should provide for the needs of his family; the law in fact imposed it upon him as a duty. "Religious study not accompanied by work of the hands is barren and leads to sin." The functions of a rabbi were purely honorific in character, dignifying, and unrelated in kind to' mercantile goods, for which one receives pay. It was forbidden to make the law a means of earning one's living or a title to glory. "He who profits by his studies or who studies for his own interest, compromises his salvation." When the religious representative showed such devotion and disinterestedness, the pious willingly submitted themselves to his authority. The spiritual heads of the communities had as great ascendency [ascendancy sic] over believing Jews as a king had over his subjects; they were sovereigns in the realm of the spirit. And Rashi in his time, because of his learning and piety, exercised the most undisputed authority. His influence though not so great was comparable, in the sphere in which it could be exercised, with that of the great Saint Bernard upon the entire Christian world, or with that of Maimonides upon Judaism in the Arabic countries. People in all circumstances and from all the surrounding countries addressed themselves to him; and to the list of his correspondents in Lorraine may be added the names of several French rabbis, the "wise men" of Auxerre, the scholar Solomon of Tours, whom Rashi calls his dear friend, his kinsman Eleazar, and R. Aaron the Elder. His correspondence on learned questions was so large that sometimes, as when he was ill, for instance, he would have his disciples or relatives help him out with it.[22]
