Maimonides calls them '''צדיקי אומות העולם''' meaning '''Righteous of the Nations'''. They are the [[Chasidei Umos HaOlam]] who have taken an oath in front of a recognised beth deen and been granted official residence status/honorary citizenship in the Land of Israel because of their outstanding righteousness among the nations of the world. Only a Tzadik umot ha Olam is an official Ger Toshav. According to Maimonides, the Official Ger Toshav can only exist when the Jubilee law is in place.
