a foreigner, or person born in another country, and therefore not ent-tled to the rights and privileges of the country where he resides. among the hebrews there were two cl-sses of aliens. (1.) those who were strangers generally, and who owned no landed property. (2.) strangers dwelling in another country without being naturalized (lev. 22:10; ps. 39:12). both of these cl-sses were to enjoy, under certain conditions, the same rights as other citizens (lev. 19:33, 34; deut. 10:19). they might be naturalized and permitted to enter into the congregation of the lord by submitting to circ-mcision and abandoning idolatry (deut. 23:3-8). this term is used (eph. 2:12) to denote persons who have no interest in christ.
