Ger Toshav (Resident Alien)
In earlier times, a Gentile living in the Land of Israel who accepted the Seven laws in front of a rabbinical court was known as a Ger toshav (literally Stranger/Resident) or "Resident Alien". Jewish law recognizes a Biblical obligation to help a Ger toshav in time of need (as opposed to the rabbinic obligation help all Gentiles who live among Jews). The regulations regarding Jewish-Gentile relations are modified in the case of a Ger toshav.
Jewish law only allows the official acceptance of a Ger Toshav as a resident in the Land of Israel during a time when the Year of Jubilee (yovel) is in effect. There is discussion in the sources as to whether some of the laws that apply to a Ger Toshav may be applied to some modern Gentiles, particularly Muslims.
A Ger Toshav should not be confused with a Ger Tzedek, who is a person who prefers to proceed to total conversion to Judaism, a procedure that is traditionally only allowed to take place after much thought and deliberation over converting.
