According to Orthodox interpretations of Halakha, converts face a limited number of restrictions. A marriage between a female convert and a kohen (members of the priestly class) is prohibited and any children of the union do not inherit their father's kohen status. While a Jew by birth may not marry a mamzer, a convert can. Converts can become rabbis. For instance, Rabbi Meir Baal Ha Nes is thought to be a descendant of a proselyte. Rabbi Akiva was also a very well known son of converts. The Talmud lists many of the Jewish nation's greatest leaders who had either descended from or were themselves converts. In fact, King David is descended from Ruth, a convert to Judaism.() In Orthodox and Conservative communities which maintain tribal distinctions, converts become "Yisraelim" (Israelites), ordinary Jews with no tribal or inter-Jewish distinctions. Converts typically follow the customs of their congregations. So a convert who prays at a Sephardi synagogue would follow Sephardi customs and learn Sephardi Hebrew.
