Proselyte

Proselyte is the anglicized form of the Greek word prosēlutos (Koine Greek: προσήλυτος, lit. 'stranger' or 'newcomer'). In the Septuagint, the classical Greek translation of the Tanakh, the term refers to someone born outside of the Jewish community who relocates to the Land of Israel and adopts, either fully or partially, the observance of mitzvot (Hebrew: מִצְווֹת, lit. 'commandments') and practice of Judaism. The term is itself a translation of ger toshav (גֵּר תּוֹשָׁב, 'resident alien'), a rabbinic designation found in the Mishnah and Talmud for a non‑Jewish resident who accepts certain commandments and protections of the Jewish community; it is distinct from a full convert (גֵּר צֶדֶק). The term also has the more general meaning in English of a new convert to any particular religion or doctrine.
