Tzadikei Umos HaOlam
צדיקי אומות העולם 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. The Official Ger Toshav can only exist when the Jubilee law is in place.
The Aramaic scriptures refer to them as מו֞מן.
