Definition of 'Alien'

From: Easton
  • 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.
  • Those who were strangers generally, and who owned no landed property.
  • 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.
