Alien

a foreigner, or person born in another country, and therefore
not entitled to the rights and privileges of the country where
he resides. Among the Hebrews there were two classes 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 classes 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 circumcision and
abandoning idolatry (Deut. 23:3-8).

This term is used (Eph. 2:12) to denote persons who have no
interest in Christ.
