During the period of the Geonim (c. 650-1050 CE), opinions on compensation shifted. It was deemed inappropriate for the leaders of the Jewish community to appear in the marketplace as laborers or vendors of merchandise, and leading a Jewish community was becoming a full-time occupation. Under these conditions, the Geonim collected taxes and donations at home and abroad to fund their schools ("yeshivot") and paid salaries to teachers, officials and judges of the Jewish community, whom they appointed. Maimonides (1135-1204), who supported himself as a physician, reasserted the traditional view of offering rabbinic service to the Jewish community without compensation. It remains the ideal. But circumstances had changed. Jewish communities required full-time rabbis, and the rabbis themselves preferred to spend their days studying and teaching Torah rather than working at a secular trade.
